Fluid under the knee what to do. Helps with fluid accumulation in the joint capsule of the knee. What are the dangers of fluid accumulation in the knee joint?

The problem that is raised in this article is very relevant at any time, under any conditions, level of life. You can encounter it in absolutely any place, under different conditions, or you may not even notice its appearance.

The purpose of this article is to help detect, prevent and treat diseases in which fluid accumulates in the knee joint, knee pain, joint tumors.

The information presented in the article will be useful to all its readers, without exception. After all, knee joint diseases can strike anyone and it does not always depend on body type, lifestyle or financial situation. In the same way, the manifestations of these diseases can be absolutely unique, although they have similar symptoms.

Structure of the knee joint

Fluid in the knee joint

The knee is considered the largest joint in the human body. When walking, the entire body weight is applied to the knee. It is for this reason that injuries in the knee area can very often be found in traumatology. As a rule, all diseases of the knee joint are the result of various falls, injuries or severe stress on the joint. One of them is considered to be fluid in the knee joint or synovitis.

Due to various diseases or injuries, fluid can accumulate in the knee joint. With this pathology, it is necessary to consult a doctor as soon as possible and begin treatment. Otherwise, the motor function of the lower extremities will be impaired.

The normal functioning of the knee joints is ensured by a complex functioning mechanism musculoskeletal system. Accumulating fluid in the knee joint can partially or completely limit its movement and also cause significant physical pain. The problem must be solved quickly, otherwise there is a risk of irreversible processes and disability.

Often, a complication of a knee injury can manifest itself in the form of an accumulation of fluid in the knee joint; if swelling of the joint occurs, swelling of varying degrees and pain syndrome can be said with almost 100 percent certainty that fluid has appeared in the knee.

In such situations, treatment consists of creating necessary conditions complete rest of the damaged joint using fixation with a bandage or pad. When synovial fluid does accumulate in the knee joint, it is usually removed by a surgeon using a syringe. In this case, local anesthesia is used.

The fluid in the knee joint may be clear, cloudy, or bloody. In addition, the severity of the pain will depend on the degree of damage to the knee.

Often, the accumulation of fluid in the knee joint is a consequence of injuries, falls or overloads. Synovial fluid is called synovium for short because it appears in the synovial membrane. For this reason, the scientific name for this disease is synovitis. The disease is quite dangerous, treatment must be started immediately.

Fluid in the knee joint, the reasons for its appearance

Fluid accumulates primarily after overloads, injuries or unfortunate falls. Most often, the injury occurs from a simple blow to the knee or after a jump from a great height.

The bones, muscles and tendons that form the knee joint are covered with a special membrane - synovial. It is practically impenetrable, serves as a kind of shock absorber, protecting the joint from damage, and ensures its physiological mobility.

The cells covering the synovial membrane secrete a liquid lubricant into the joint space, ensuring the free functioning of bone and cartilage surfaces. If such fluid is produced more or less than normal, physical pain of varying intensity, pathological changes occur in the cartilage and bone tissue of the knee.

There are several main factors why synovial fluid in the knee begins to secrete in larger volumes than necessary. Experts identify the following reasons:

injuries;
inflammatory processes infectious nature;
malignant neoplasms;
osteoarthritis;
allergic (immune) reactions;
gout;
blood clotting disorder.

The accumulated liquid may be cloudy or clear and have different colors (white, red, pink, yellow). It all depends on the cause of synovitis. Turbid, yellowish liquid indicates the infectious nature of the inflammation; pink or red color indicates hemorrhage inside the synovial cavity due to injury or bleeding disorder.

The complex structure of the knee joint and the heavy loads it experiences make it vulnerable. Sports, potentially dangerous species work, accidents are common reasons injuries After a knee injury, fluid accumulates inside the synovium for 2-3 days.

Osteomyelitis, bone tuberculosis, bacterial sepsis are infectious causes that cause fluid accumulation in the knee joint. Bacterial infection of the knee joint may occur as a result of an open or closed injury. Rheumatoid arthritis, bursitis and gout cause physiological changes work of the knee joint, causing the formation of significant volumes of fluid in the synovium.

Malignant tumors and sarcoma, which are localized in bone and cartilage tissue, cause significant changes in the function of the knees and cause the appearance of fluid. Fluid in the knee joint may appear due to an inadequate reaction of the body in response to the penetration of an allergen or an autoimmune process. Blood clotting disorders, including hemophilia, lead to the filling of the synovial cavity with red fluid.

General symptoms

Typically, symptoms of fluid in the knee after an injury include:

sharp, aching, dull pain in the knee;
swelling in the joint, pronounced or barely noticeable;
stiffness of movement: with a large accumulation of fluid, it is difficult for a person to move, it is impossible to bend the leg;
knee size increases;
body temperature rises;
a seal appears under the skin in the joint area;
the skin turns red;
Headaches and chills are possible if the pathology is caused by an infection.

But chronic synovitis is characterized by less severe pain. In other words, the joint fills with fluid gradually. That is why, with a long-term course of the disease, deforming arthrosis may appear.

In addition, there is also reactive synovitis of the knee joint, which is considered allergic type of this disease and is caused by mechanical or toxic influences and often acts as a manifestation allergic reaction.

Crunch in the knee

Let's talk about such phenomena as quiet clicks and crackles in the legs, which then become louder and are sometimes accompanied by painful sensations. Therefore, you need to think about what to do if you have a crunch in your knee immediately after it appears. Typically, the sooner treatment for a crick in the knee begins, the greater the chance that it will be effective.

The causes of a crunch in the knee joint may be the consequences of joint injury or damage to cartilage, salt deposits, vitamin deficiency, endocrine disorders, increased mobility of the head or general instability of the joint.

Sometimes a crunch appears as a result of a violation of congruence, i.e. exact match articular surfaces, as a result of which they can touch, making characteristic sounds.

For correction incorrect position articular surfaces, you need to consult a specialist; independent attempts to straighten the knee joint can lead to serious injury or even disability. A crunch in the knee can be one of the symptoms of arthritis or arthrosis, as well as pathological salt deposition.

Prevention of a crunch in the knee lies, first of all, in the correct balanced diet and prevention mechanical damage knees. In case of injuries and sprains of the knee joint, it is imperative to apply a fixing bandage to the damaged joint, otherwise this may subsequently lead to displacement of the articular surfaces or the development of increased mobility and instability of the joint, which in turn is usually accompanied by a crunch in the knee.

Diagnosis of pathology

If there is an accumulation of fluid, treatment begins only after the picture of the origin of the pathology has been established. To do this, it is necessary to conduct a number of diagnostic studies, which include examination of the limb, taking an anamnesis, interviewing the patient and instrumental (hardware) examinations. The data obtained with their help helps to reliably determine where the fluid is localized in the knee joint, to identify the causes and treatment of the pathology.

The most informative diagnostic tools are:

X-ray of the knee;
ultrasound examination;

Patients also need to donate blood for laboratory testing, and sometimes undergo an aspiration procedure, that is, pump out fluid from the affected knee to determine its composition.

Reactive synovitis

This form is considered as secondary synovitis that occurs against the background or as a complication of another disease. In fact, this is an inadequate allergic reaction of the body, which appears as a result of mechanical or toxic effects on the affected joint.

Therefore, treatment for a diagnosis of reactive synovitis is aimed at eliminating provoking factors.

The reasons for this reaction of the body may be other diseases of the knee joint:

With gonarthrosis, synovitis of the knee joint can be observed as a moderately severe complication already at the second stage of the disease. In such a situation, doctors try not only to eliminate accumulated fluid from the joint, but also make every effort to regenerate damaged joint tissue.
In arthritis, synovitis of the knee joint is quite common. The inflammatory process in the joint, caused by autoimmune or metabolic failures, is almost always accompanied by an accumulation of fluid in moments of exacerbation.
Synovitis and bursitis of the knee joint are considered paired diseases. Bursitis is a narrower concept of inflammation that extends directly to the bursae. When the joint capsules become inflamed, synovitis acts as the main symptom of the disease. The most pronounced synovitis of the knee joint is observed with superapatellar bursitis, when the synovium over the kneecap becomes inflamed.

The synovial membrane can also become inflamed due to:

allergic reactions;
atopic dermatitis;
eczema, hemophilia;
autoimmune conditions;
endocrine pathologies;
metabolic disorders.

Post-traumatic synovitis

Synovitis, which occurs as a consequence of joint injuries, is a common clinical picture.

The synovial membrane can become inflamed:

if the meniscus is damaged;
after ligament rupture;
due to a direct or glancing blow;
after dislocations or subluxations of the knee;
in the presence of microcracks in the joint;
for fractures;
due to scratches, wounds of surface tissues.

When treating post-traumatic synovitis, attention is paid to restoring the integrity of the damaged parts of the joint. Post-traumatic synovitis is characterized by acute course diseases. Inflammation resulting from chronic injuries occurs as moderate synovitis.

Exudative synovitis

This disease is associated with instability of the knee joint. With instability, movements are not carried out in full, which provokes irritation of the synovial membrane and, as a consequence, exudative synovitis with a significant accumulation of exudate.

This form of synovitis occurs:

for knee deformation after injuries, as well as degenerative processes caused by rheumatism, gout;
in case of ligament insufficiency, which appears as a genetic anomaly or due to low joint mobility;
with direct injury to the joint, when the blow is directed perpendicular to the articular surface;
with a meniscus injury that provokes irritation of the synovial membrane.

Treatment of exudative synovitis of the knee joint is aimed at restoring stability and mobility of the joint.

Infectious synovitis

Infections most often enter the joint due to injury. The synovial membrane reliably protects the joint from infection. The slightest damage “opens the gate” for infection.

Infections can enter in various ways:

contact – through damage to the skin;
hematogenous – through the bloodstream if the patient has infections in the body;
lymphogenous - along the lymphatic bed.

Infection occurs with both pathogenic and opportunistic particles:

streptococcus;
staphylococcus;
pneumococcus;
tuberculosis microbacterium.

Viral infections can also provoke inflammation in the synovium. So, synovitis can be a consequence of influenza, ARVI.

Symptoms of the acute stage of the disease

The inflammatory process can develop over several days, or it can be quite rapid and appear within a couple of hours.

The first sign includes an increase in the volume of the joint, in which the contours of the knee are smoothed. The process is associated with the accumulation of fluid of various etiologies in the cavity. The severity of swelling depends on the volume of accumulated fluid. Visually, there is a slight increase in the knee.

This distinctive feature helps differentiate the disease from hemarthrosis, in which the knee joint rapidly enlarges in literally a matter of minutes and significant swelling is observed due to accumulated blood.
In acute synovitis of the knee joint, the motor abilities of the knee are impaired. Restriction of movement is caused by swelling and pain syndrome. Despite this, the patient is able to lean on the affected limb and perform flexion movements.

Minimal synovitis of the knee joint may be generally painless. Most often, the pain is not intense, but is perceived by the patient as discomfort with unpleasant pulling or dull sensations. Pain manifests itself on palpation of the affected area. With such inflammation, there are no local changes in the color and temperature of the skin of the joint.

When synovitis is purulent, the symptoms are expressed:

throbbing, bursting painful sensations;
the appearance of fever;
general malaise, accompanied by weakness, loss of appetite, muscle pain and headaches;
significant swelling of the affected joint;
painful movements;
hyperemia skin above the site of pathology;
local temperature increase.

The disease usually affects one of the joints. Bilateral damage can be observed with an infectious or autoimmune origin. In the absence of adequate treatment, acute synovitis of the knee joint can become chronic.

Symptoms of the chronic stage of the disease

Chronic synovitis of the knee joint is not such a rare type among other types of this disease. It occurs as a result of an untreated acute form or chronic instability or deformation of the knee joint.

Patients experience symptoms such as:

general weakness;
fatigue when moving;
minor limitations in the mobility of the knee;
intermittent aching pain.

In the chronic form, swelling may not be visible at all or may have a minor manifestation. If you do not start urgent treatment of chronic synovitis, over time the disease progresses and causes complications.

Due to the constant accumulation of a liquid substance that does not have time to dissolve, hydratosis occurs. With prolonged chronic dropsy, secondary pathologies develop in the form of sprains, joint instability, subluxations and dislocations. Under the influence of inflammatory fluids, the synovium undergoes secondary sclerosis, morphological changes. The loss of its functional abilities of the synovial membrane leads to worsening pathological process.

As a result, the articular surfaces are destroyed, and special forms of transformations arise in synovitis that require surgical intervention.

Synovitis in children

The clinical picture of synovitis of the knee joint in a child is practically no different from the pathology in adult patients. However, childhood synovitis tends to develop more rapidly with severe degrees of damage. This is explained by the characteristics of a growing organism with more accelerated blood flow and metabolism.

Therefore, it is important to begin treatment of synovitis in children at the first suspicion of the disease.

Types of pediatric joint pathology are associated with:

with a high incidence of injuries;
With infectious diseases;
with allergic reactions;
with metabolic disorders.

IN separate species They distinguish transient synovitis in children, which is considered to pass. It occurs in children from 1.5 to 15 years old. It is characterized by pain when moving and severe lameness. However, the disease tends to go away within a week without causing serious complications.

Doctors characterize this type of disease as a natural immune response of babies to infection. respiratory tract. Although the disease remains unexplored until the end.

When infected with viral infectious diseases, the child’s immunity is activated, resulting in attacks on the joint with a temporary inflammatory process. In this case, during diagnosis, excess fluid is clearly observed.

Pain and lameness disappear 3-4 days after the exacerbation. If symptoms do not disappear for more than 7 days, additional studies are required.

Forecast

The prognosis for synovitis depends on the following factors:

general condition of the patient’s body;
level of pathogenicity of the microflora, if the form is infectious);
whether treatment was undertaken in a timely manner.

Recovery may be complete. The patient may retain mobility of the joint. This outcome is most often observed in diseases of the serous and allergic type.

But it is also possible to limit the mobility of the joint or completely lose the ability to move. At purulent form The disease sometimes poses a threat to the patient’s life, as sepsis develops.

Surgical treatment

There are several treatment options for conditions associated with fluid accumulation in the knee. Treatment must eliminate the causes and symptoms of the disease. What to do in each specific case should be determined by the attending physician based on the results of the examination and diagnosis.

How to get rid of fluid in the knee? A special needle is inserted into the joint, and the liquid is pumped out with a syringe. It is quite difficult to pump out the fluid without anesthesia. The patient is first given powerful analgesic drugs or local anesthesia. Then they conduct research on the obtained material. Even if the pathology is not infectious.
Based on the results of the analysis, the doctor will draw conclusions about what pathological processes caused the formation of fluid.

He then decides what therapy to prescribe to prevent relapse in the joint structures. Swelling of the legs is relieved after the knee is freed from pathological fluid.

With a significant volume of fluid and changes in the structure of the joint, conservative treatment is not always effective. For this reason, the doctor may decide to perform such a procedure. If the fluid has deformed the joint, prosthetics are performed. The main treatment for fluid in the knee joint is to remove the fluid from the damaged joint.

The procedure is performed in an operating room, usually without anesthesia. The doctor carefully inserts a thin special needle into the cavity of the affected joint, in which fluid has accumulated, and is sucked out with a syringe. When the procedure is completed, antibiotics are injected into the vacated cavity, regardless of whether an infection is suspected.

After the operation to remove the fluid, the patient is placed in a room to ensure complete rest of the joint, this is done using a pressure bandage or knee brace.

Further treatment for the occurrence of fluid in the knee joint involves the use of anti-inflammatory drugs, of which the most effective, in our opinion, are Voltaren and Diclofenac.

In addition, in the process of treating fluid in the knee joint, doctors eliminate not only the inflammation, but also the underlying cause of its occurrence. Install accurate diagnosis Only a specialist doctor can do it: an orthopedist or a rheumatologist, because if the root cause of the inflammation is not found, the fluid will soon appear again, and treatment will have to be performed all over again.

Drug therapy

Drug therapy in the treatment of synovitis of any etiology is used to eliminate symptoms, as well as to relieve inflammation. It is worth noting here that the decision on how to treat fluid in the knee joint with medications is made solely by the doctor based on the results of the examination.

In most cases, patients are prescribed certain groups of drugs. NSAIDs – for pathologies of any origin. They help relieve swelling and pain. Ibuprofen and Diclofenac are considered the most effective. Along with oral forms It is recommended to use an ointment that contains these drugs.

Antibiotics are used when the synovial fluid contains pus. Since it is possible to get rid of inflammation caused by microorganisms only with the use of such drugs, they are prescribed orally, in the form of injections, or for direct injection into the knee joint after the fluid has been pumped out. The specific type of antibiotic is determined after bacterial culture to determine the sensitivity of the microorganism to certain substances.

Anti-inflammatory corticosteroids (glucocorticoids) help relieve inflammation and limit the influence of the underlying pathology on the formation of excess fluid in the knee. The most commonly prescribed medications are Dexamethasone, Prednisolone and Triamcinolone.
Antihistamines are prescribed only when the accumulation of synovial fluid is directly related to severe autoimmune disease or rheumatoid arthritis.

Any medicine can be taken after it is approved by a doctor. This happens in most cases after the liquid fraction has been pumped out from the affected joint.

Surgical treatment

If the damage to the synovial cavities has reached its maximum and there is a danger of their rupture, as well as if conservative methods of therapy are ineffective, the patient may be referred to arthrocentesis - a procedure for opening the bursa and pumping out fluid using a special syringe with a needle.

The first question patients ask when referred for this procedure is whether it hurts to remove fluid from the knee joint. Everything goes under local anesthesia, since removing liquid through a puncture without using it will be very painful. During the operation, the patient does not feel pain, but as the bursa empties, he may notice a decrease in pressure inside the knee, especially if there is purulent inflammation.

Next, the doctor injects medications into the joint capsules using a syringe, since removing the fluid is not the only goal of the operation. Corticosteroids or antibiotics placed inside the inflamed bursa help to quickly cope with the pathological process.

When the process has gone far, which is why the joint is deformed, the patient is shown prosthetic replacement of the joint or its individual elements (depending on the degree of deformation).

Conservative treatment

Conservative treatment aims to relieve symptoms of fluid accumulation in the knee joint, and in case of infectious and allergic diseases– eliminate the causes of pathology. Scroll medicines determined by the doctor.

Symptoms of pain and inflammation can be relieved with the help of drugs from the group of non-steroidal anti-inflammatory drugs. Preparations of ibuprofen, paracetamol, diclofenac, ketoprofen, indomethacin eliminate pain, inflammation, and reduce temperature.
Treatment with antibiotics effectively eliminates purulent inflammation. Antimicrobial drugs are prescribed after determining the sensitivity of the bacteria that caused the pathology. A bacterial culture of material taken from the affected joint should be done. This will allow you to select an antibiotic with maximum effectiveness and quickly cope with the disease.

Treatment with antihistamines is used when the cause of fluid in the knee joints is associated with autoimmune diseases, rheumatoid arthritis. Suprastin and tavegil are used. In severe cases, injections of glucocorticoid drugs can be given: dexamethasone, prednisolone, betamethasone. Sometimes such injections are performed directly into the joint.

Drugs from the group of non-steroidal anti-inflammatory drugs relieve inflammation and symptoms of the disease.
Ibuprofen, Paracetamol, Indomethacin will reduce the temperature, eliminate pain and inflammation.

Antibiotics eliminate purulent inflammation. For example, Nimid. This is an analgesic and anti-inflammatory drug. It is used up to 4 times a day. Contraindicated during pregnancy and lactation. You can also rub your knee with Fastum and Voltaren-gel ointments. They also contain antibiotics.

Antimicrobial agents are prescribed after determining the sensitivity of the bacteria that caused the accumulation of fluid in the knee. A bacterial culture of material is taken from the affected joint.

Antihistamines are used if fluid in the knee appears due to autoimmune diseases (Suprastin, Tavegil).
Taking immunostimulating drugs, vitamins, calcium.

The accumulation of fluid in the knee joint can be a symptom of dangerous diseases. Self-medication is contraindicated.
It threatens the possibility of the formation of a chronic form, which will cause complications and, possibly, disability.

Traditional medicine

How to remove fluid from the knee joint folk remedies? Treatment with folk remedies for fluid in the knee joint should be carried out only in combination with conservative methods therapy and only after the doctor allows it.

The beets are washed, peeled, and grated. Wrap it in a cloth and apply it to the affected knee overnight. Compresses are applied until recovery.
The bark of an elderberry branch is placed on a cabbage leaf and applied to the knee. The dressing is changed after the cabbage and bark have dried. Apply until recovery.

30 bay leaves are poured into two glasses of water, boiled for 3 minutes, the water is poured into a thermos and left for 4 hours. Afterwards they filter. Drink internally in small sips all day long. Course duration - 3 days. Take a break and repeat the treatment.
Bay leaves are also used to make oil. Two tablespoons of crushed dried product are poured into a glass sunflower oil(you can take olive or corn). Place it for 7 days in a dark place. The infusion is rubbed into the knee three times a day until full recovery.
Mix a bottle of pharmaceutical bile, two glasses of crushed fruits horse chestnut and three chopped aloe leaves. Pour two glasses of 70% alcohol and leave for 10 days. Make a compress at night: after 10 compresses, a week break, and again 10 compresses.
For inflammation and accumulation of fluid, which is accompanied by pain, prepare the following tincture: fill a half-liter jar with dodder, fill it completely with vinegar, leave for five days. Soak a cloth in the tincture, apply it to the affected knee, wrap it in a bandage or polyethylene, then insulate it with a scarf or towel. This tincture is also effective for arthrosis, polyarthritis, shoulder bursitis, bursitis elbow joint.
A glass of crushed comfrey is mixed with 200 g of chopped lard. The composition is placed in the refrigerator for 5 days. Afterwards, rub the ointment into the knee twice a day at night. The knee is then bandaged. Add half a glass of rye grains to a liter of water and boil for 20 minutes.

I recently watched a program on Channel One, it was also about this Federal program to combat joint diseases talked. It is also headed by some famous Chinese professor. They say that they have found a way to permanently cure joints and backs, and the state fully finances the treatment for each patient.

The knee joint is one of the most complex joints in our body. Every day a colossal load is placed on the knees, but a person does not feel this if the joints are healthy. If any disease develops or injury occurs, the function of the joint is impaired. The person is experiencing pain or other discomfort during movements, which leads to a decrease in quality of life, and in some cases even to disability.

One of common symptoms, which is observed in many diseases and injuries of the knee, is swelling and an increase in the volume of the joint, while, as a rule, fluid accumulates in the knee joint. Why does this happen, what to do in this case and is this phenomenon dangerous? we'll talk in this article.

Synovial fluid and its function

The knee joint with all its anatomical components is enclosed in a dense connective tissue joint capsule. The inner surface of this capsule is called the synovium (synovium). It consists of a single layer of epithelial cells that produce synovial fluid.

For normal functioning joints, this liquid is very important, despite the fact that its quantity is very tiny (2-3 ml). This is a transparent or slightly yellowish thick elastic mass that fills the joint cavity and acts as an intra-articular lubricant. It prevents friction of the articular surfaces of bones and premature wear and destruction of hyaline cartilage, ensures mobility, and has shock-absorbing capabilities (dampens external shocks, protecting joint components from damage).

Also, synovial fluid nourishes the cartilage of the joint, since it does not have its own blood vessels and receives all the necessary substances by diffusion from the intra-articular fluid.

Both a lack of this fluid and its excess are dangerous to health. In both cases, the function of the joint is disrupted and a person’s motor activity suffers.

Causes of fluid accumulation in the knee joint

It is important to understand that fluid accumulation in the knee joint is not separate disease but only a symptom large quantity pathological conditions both injuries and diseases (acute or chronic).

For some reason, the synovium becomes inflamed, thickens, becomes impermeable and begins to produce excess fluid. This leads to its accumulation in the joint cavity, swelling, an increase in the volume of the joint, loss of its function, and pain. Doctors call this condition synovitis, and the accumulation of fluid itself is called hydrarthrosis; if blood accumulates in the joint cavity, then this condition is called hemarthrosis.

Depending on the composition of the fluid, synovitis can have a different character:

serous,
fibrinous,
hemorrhagic,
purulent.

Depending on the duration of the disease, acute and chronic forms are distinguished. Depending on the reason why fluid collects in the knee joint, synovitis can be:

post-traumatic (after injury),
allergic,
infectious,
aseptic (non-infectious).

You should be aware that fluid can collect not only in the articular cavity of the knee joint. This joint has several additional synovial cavity structures (bursae). They protect the connection and perform shock-absorbing functions. Liquid can accumulate separately in the cavities of such joint capsules. In such a situation we are talking about bursitis.

List of diseases that most often lead to fluid accumulation in the knee joint:

injuries (bruises, dislocations, fractures, sprains and ruptures of ligaments, menisci);
osteoarthritis;
rheumatoid arthritis;
rheumatoid arthritis;
gout;
hemophilia (leads to hemarthrosis);
infectious and reactive arthritis;
allergic reactions.

If after thorough examination The cause of synovitis cannot be detected, then they speak of an idiopathic variant of the disease.

Symptoms

Typically, one knee is affected. Synovitis may occur acutely or may progress over several days, weeks, or even months.

Signs that indicate increased formation of intra-articular fluid and its accumulation in the joint cavity:

pain syndrome (pain can be bothersome at rest, or may appear during active or passive movements);
change in the normal configuration of the joint: its swelling, increase in volume, smoothness of contours, disappearance of anatomical landmarks, for example, pits, bony protrusions;
the skin over the joint may be unchanged, but if there is a lot of fluid in the joint, it becomes tense, shiny, and in the case of purulent inflammation, it becomes cyanotic or turns red, and the local temperature of the skin rises;
the function of the joint suffers: the patient cannot fully perform the necessary movements due to pain and swelling.

If a chronic form of synovitis occurs and no measures are taken to treat it, the joint begins to deform. This leads to permanent impairment motor function and disability.

Treatment methods

The tactics and choice of treatment for fluid accumulation in the knee joint depends on the cause that caused the disorder and the rate of increase in symptoms. Synovitis can be treated conservatively and surgically.

Conservative methods

Conservative therapy is prescribed not only to eliminate the symptom, that is, accumulated fluid, but also to remove the cause that caused it.

A tight elastic bandage or orthosis is applied to the affected joint. This eliminates mobility in the joint, which can contribute to the progression of the disease. At this stage of therapy, any physical activity. Strict bed rest is prescribed.

Almost all patients are prescribed drugs from the group of non-steroidal anti-inflammatory drugs. They eliminate pain, help reduce the activity of the inflammatory process, lead to stabilization and then regression clinical symptoms. In the case of a chronic process, glucocorticosteroid anti-inflammatory drugs can be prescribed for injection directly into the cavity of the diseased joint.

If synovitis is infectious in nature, then it is necessary to prescribe antibacterial agents. If the symptoms are caused by an allergic process, then the treatment program includes antihistamines. In the case of autoimmune pathology (rheumatoid arthritis, etc.), cytostatics, corticosteroids and other basic anti-inflammatory drugs are used.

In case of hemarthrosis, special hemostatic drugs are prescribed. Patients with hemophilia are given deficient clotting factors.

When it is possible to remove the signs of active inflammation, they resort to a rehabilitation period. Assign physical therapy, various physical procedures.

Operative techniques

Unfortunately, conservative therapy does not always bring the desired effect. If the volume of fluid is significant, there is no effect from the medications used, then surgical treatment is used. For this purpose, 2 procedures are carried out:

Arthrocentesis is a puncture of the joint with a syringe and a needle and pumping out fluid. Immediately after the elimination of exudate from the joint cavity, antiseptics, antibiotics, and anti-inflammatory drugs are administered inside so that the fluid does not accumulate again.
Arthroscopy is an operation that is performed using special endoscopic instruments. It makes it possible not only to pump out fluid, but also to examine the joint and find the cause of pathological symptoms.

To sum up, it must be said that for successful treatment effusion in the knee joint, you need to find its cause. Only complex therapy can prevent recurrent synovitis and its consequences. Therefore, if you identify such a problem in yourself, mandatory come through comprehensive examination.

Directions for treating synovitis
Stages of treatment
Treatment methods

Synovitis of joints is inflammation of the synovial (inner) membrane that covers the joint cavity. During the inflammatory process, effusion is formed, fluid accumulates in the joint capsule. When infection penetrates, the effusion turns into purulent contents - at this point purulent synovitis develops. More often, inflammation affects the knee joint, since it experiences considerable stress.

Based on the reasons that caused the disease, infectious or non-infectious synovitis is distinguished, based on the nature of its course - chronic or acute.

Directions for treating synovitis

As a rule, the symptoms of synovitis of the knee joint are clearly expressed: there is pain, there is a change in the shape and limitation of joint mobility, and the temperature rises. A person should consult a doctor as soon as possible. Treatment of patients usually involves complex therapy, taking into account the reasons that caused the disease, as well as the course of the pathological process.

To eliminate joint functions impaired by inflammation, doctors recommend general strengthening therapy, physiotherapy and physical therapy. The actions of doctors are, of course, aimed at identifying the causes and eliminating them, as well as at removing, first of all, such obvious severe symptoms illnesses such as pain and dysfunction. Surgery, as one of the treatment methods, is rarely prescribed if there is no positive effect from conservative treatment methods or if there is a threat to the patient’s health (the development of sepsis).

Stages of treatment

Usually, the attending physician decides how to treat synovitis of the knee joint, based on the reasons that caused it, the stage of the disease and the nature of the course. The doctor must prescribe a comprehensive examination of the entire body in order to find out what specifically triggered the development of knee synovitis, monitor the development of inflammation, and predict possible complications at the patient.

First, a puncture of the diseased joint is performed. The procedure is performed experienced surgeons. Anesthesia is not required during this procedure, since the patient practically does not feel pain, only some discomfort. The specialist inserts a thin needle into the joint area and sucks out synovial fluid (effusion). The resulting exudate is sent to the laboratory for testing.

The next stage of treatment is joint immobilization. Its goal is to ensure complete peace. Doctors apply splints, plaster splints, and pressure bandages. Choice of the most suitable method temporary immobilization is determined by the nature of the disease. So, with minimal synovitis of the knee joint, it is enough to use pressure bandage or a special patella. And if infectious synovitis is accompanied by severe damage to the joint, rigid immobilization with plaster splints or splints will be required. This stage of treatment usually does not exceed seven days.

Treatment methods

Methods of drug treatment of the disease

Taking medications prescribed by a doctor leads to a speedy recovery. If you do not follow your doctor's instructions, you may experience various complications, including joint destruction, sepsis and suppuration.

There are several groups of drugs prescribed for the treatment of synovitis:

Surgical method of treatment

There are cases when conservative treatment of synovitis of the knee joint does not produce results, but, on the contrary, contributes to the progression of the disease. This is evidenced by rare reviews from patients. In such cases, doctors use methods surgical treatment- perform total or subtotal synovectomy. During the operation, the surgeon opens the joint cavity, performs resection of the synovial membrane, and removes foreign bodies from the joint cavity.

Afterwards, anti-inflammatory, hemostatic and antibacterial therapy is carried out. During the recovery period, rest and reduction of stress are indicated to prevent the re-development of synovitis. As soon as the patient’s condition improves, the doctor prescribes physiotherapy and exercise therapy to “develop” the joint.

Folk remedies in the fight against disease

There are quite a few folk ways treatment of this disease. However, they are not able to completely cope with the disease on their own, even if the synovitis of the knee joint is moderate. They are allowed to be used in conjunction with other treatment methods, with the obligatory approval of a doctor.

Medicinal comfrey is useful. Compresses promote rapid tissue healing and prevent the development of necrosis.

You can prepare an infusion for drinking. To do this, mix crushed herbs of mistletoe, echinacea, eucalyptus, yarrow, tansy, thyme, oregano, and birch leaves. Take a spoonful of the mixture and pour a cup of boiling water, leave for about an hour. The solution is then filtered and drunk throughout the day between meals.

Let us note once again that any self-treatment measures must be coordinated with a doctor. For example, the cause of reactive synovitis of the knee joint may be an allergy. Therefore, in order not to harm your health, you should go through medical examination, on the basis of which the doctor will determine the exact causes and prescribe comprehensive effective treatment.

Timely access to a medical facility increases the chances of speedy recovery and return to old life. The main thing is not to start the disease. Modern methods Treatments for synovitis are quite effective, and the number of relapses is minimal.

Fluid in the knee joint: what to do if there is accumulation in the knee under the cup, symptoms, prevention

The knee joints are considered the largest and most frequently injured. It is on them and the feet that the entire weight of a person’s body is supported while walking. Therefore, knee injuries are quite common, especially in children, adolescents and obese people. Knee joints can be damaged in a child or adult due to a fall, strong blow or excessive stress on the lower limbs.

If you do not start treating your joints in time, a knee injury can cause complications. It is very common to observe fluid accumulation in the knee joint or synovitis. If the victim has swelling in the knee area, swelling of varying degrees, and the patient feels severe pain, doctors diagnose fluid in the knee joint.

In this case, the first step is to create all the conditions so that the damaged joint is at complete rest. To do this, use a fixing bandage or pad. If synovial fluid has accumulated in the meniscus, the doctor will prescribe its removal using a special syringe using local anesthesia.

The fluid in the knee may be clear, cloudy, or bloody appearance. The degree of damage depends on how badly the knee is damaged. pain at the patient. Fluid often accumulates in the knee joint due to excessive stress, a fall, or physical trauma.

Since fluid accumulation occurs in the synovium, it is called synovium. Based on this, the name of the disease synovitis, which can be seen in the photo, was formed.

Because similar disease is very dangerous for the health of both children and adults; it is necessary to begin treatment immediately as soon as fluid is detected in the knee joint.

Why does fluid accumulate in the knee joints?

Since the knee joints are often injured, in some cases fluid in the form of water accumulates in them.

The reasons why fluid may accumulate in the knee joint can be different:

The meniscus may be damaged;
The accumulation of fluid was due to hemorrhage in the knee joints;
If the ligaments are damaged;
If the injury resulted in a broken bone.

Most often, the knee injury shown in the photo occurs due to the fact that a person lands unsuccessfully on his feet, jumping from a height, or the kneecap hits something hard.

Such knee joint disorders often lead to the formation of fluid in the knee.

Symptoms of fluid accumulation in the knee

Typically, symptoms of the disease cannot be detected immediately after damage to the limbs has occurred, but only after several hours or even days. If a knee injury occurs, the joint literally immediately swells and swells. In some cases, bleeding into the meniscus may occur. The symptoms include severe pain.

The main sign that fluid has accumulated in the joint is a greatly enlarged knee. Due to the appearance of fluid in the meniscus, deformation of the joint occurs, which is why the patient is practically unable to move the leg. Dumb and severe pain is also considered the main symptom of the disease.

As a result of a knee injury and fluid accumulation in the meniscus, as in the photo, the victim may experience the following symptoms:

Gradual increase in pain;
Increased body temperature;
Increase in knee size.

Meanwhile, there is also a chronic type of synovitis, in which the patient does not feel severe and severe pain. The causes of the development of chronic disease are associated with the gradual accumulation of fluid in the joints.

If the disease is not detected in time and does not begin necessary treatment, the patient may develop arthrosis deformans.

Also modern medicine subdivides reactive synovitis, which develops in the knee joints due to an allergic reaction of the body to an external irritant. The disease is caused by mechanical or toxic influence, especially worth paying attention to. if your knee hurts after a fall.

Who is susceptible to the disease

Synovitis occurs most often in people who have a natural predisposition to this disease.

Fluid accumulation in the knee joints can occur in overweight people. They connect this with what such people experience every day heavy load on the feet, which is exerted by large body weight. Due to the pressure of weight, the cartilage in the joints can become damaged, leading to water accumulation.
In old age, after 50 years, a person’s structure of bones, feet and joints changes. Over the years, joints cannot function fully, the tissues connecting them lose elasticity, so tendons and cartilage can be easily injured. For this reason in old age people very often turn to an orthopedist.
People involved in sports at a professional level are very often injured as a result of a fall or collision. Feet and knees receive unnecessary stress during training. For this reason. Despite their young age and low weight, athletes often have problems with their knee joints. Moreover, the diseases are often chronic in nature.

How is the disease treated?

What to do if a patient exhibits symptoms of synovitis? Usually the treatment for the disease is to get rid of the accumulated water in the knee joint. Removal of fluid in the meniscus is carried out in the operating room without anesthesia.

The doctor carefully inserts a special thin needle into the cavity of the damaged knee joint, after which the accumulated water is sucked out using a syringe. After pumping has been carried out, treatment continues with the introduction of antibiotics into the joint cavity, even if there is no infection at the site of injury.

If in the future water forms in the meniscus again, you can get rid of the fluid by taking medications. Most effective medicines Diclofenac and Voltaren are considered.

To avoid having to do the procedure again, you can get rid of accumulated fluid forever if you remove the reasons for its appearance. A rheumatologist or orthopedist will help you find out why water accumulates in the joints and what needs to be done to remove fluid from the meniscus.

Otherwise, if treatment is not started, the disease may lead to complications.

Treatment with folk remedies

Once the causes have been removed, treatment can be continued with well-known and effective folk remedies.

To prepare an ointment from the comfrey plant, you will need one glass of dry crushed herb and 200 grams of lard. Comfrey is thoroughly mixed with lard and the resulting composition must be refrigerated for five days. Received healing ointment will get rid of pain and swelling. It is applied to damaged knee joints twice a day. Additionally, the knee should be secured with an elastic bandage.
No less effective means from the disease are healing infusions. To prepare rye broth you will need one liter of clean water and half a glass of rye grains. Grains are poured into water and boiled for twenty minutes. Afterwards, the resulting broth must be cooled. And two teaspoons of barberry, 0.5 kilograms of honey, 200 grams of vodka are added to it. The mixture is thoroughly mixed and placed in a dark place for three weeks. The decoction is taken two tablespoons three times a day before meals.
Bay leaf oil will remove residual fluid and heal sore joints. Two tablespoons of dry bay leaf are poured into one glass vegetable oil. The resulting composition must be infused for a week. Ready oil rubbed into joints three times a day.

Modern medicine knows a huge number of diseases in which fluid accumulates in the knee joint. In case of delay in treatment, the consequence of this process may be a violation of motor function.

The role of fluid in the knee joint

A strong, impenetrable connective tissue synovial membrane surrounds bony joint and tendon muscles in the knee. It serves to limit the mobility of the joint and to protect it from possible damage. With the help of epithelial cells of the inner layer of the membrane, a special fluid is secreted into the joint space, which is lubricant for cartilaginous surfaces in contact during the movement of the legs and absorbing external shocks.

The lack of fluid in the knee joint and its excess are considered a pathology, because this is a disruption of the normal functioning of the joint and causes pain of varying intensity.

Causes of fluid appearance

The accumulation of fluid in the knee joint causes inflammation of the synovium, which is called “synovitis.” The reasons for its development are different:

The inflammation is aseptic. Characterized by the fact that as a result laboratory research liquid, no pathogenic microorganisms or pus are found in it. It can appear after a knee injury. It may also appear as a consequence of acute viral infection with reactive arthritis or after hypothermia. Or it may result from the accumulation of metabolic products in the joint capsule of the knee (in case of gout, urea crystals).
The inflammation is purulent. It is characterized by the penetration of pathogenic microorganisms into the joint and their reproduction. Purulent arthritis can be dysenteric, tuberculous, chlamydial, staphylococcal or gonorrheal. Often the cause of purulent inflammation is severe knee injuries.
Immune inflammation. It is characterized by the fact that the appearance of excess production of synovial fluid manifests itself in response to damage to the epithelium by pathological immune complexes (with rheumatism, rheumatoid arthritis or severe allergic reaction).

Fluid accumulation in the knee joint

Symptoms of the disease

Clinical symptoms of fluid in the knee joint are as follows:

limitation of motor function (limiting sensations when trying to fully bend the leg);
swelling around the knee that is dense and elastic to the touch;
testing pain when moving the leg;
redness of the skin or feeling hot.

fluid accumulation in the leg

Treatment

Treatment in the acute period of the disease begins with providing injured limb maximum peace. In this case, it is recommended to keep the leg in a half-bent position, placing a soft cushion or high pillow under it to relax the muscles.

IN complex treatment synovitis, in which fluid collects in the knee joint, includes:

The use of painkillers internally and externally in the form of gels or ointments (paracetamol, cinquefoil, ketorol).
Taking nonsteroidal anti-inflammatory drugs to reduce pain and intensity of the pathological process. (ibuprofen, voltaren, indomethacin, naproxen, nimesulide).
The use of steroid drugs for immune complex inflammation. They help reduce the production of inflammatory fluid.

During treatment purulent arthritis use systemic and intra-articular antibacterial therapy . The choice of drug is made depending on the types of pathogenic microorganisms and their sensitivity.

intra-articular antibiotic therapy

For an injury that causes excess fluid to accumulate in the knee joint, cool packs are used.

When treating purulent synovitis, ointments are applied, which contain antiseptic, antibacterial and absorbable components.

Fluid is pumped out of the knee joint during joint puncture, after which an antibiotic or steroidal anti-inflammatory drug is injected into it. Fluid in the knee joint cannot be ignored, since the disease can become chronic and lead to impaired motor function of the joint.

When moving and walking, a person’s knee joint experiences the maximum load. To reduce tension, synovial fluid is present in the cavity of the interosseous joint. Using synovial fluid naturally the load is relieved and knee mobility is ensured.

An increase in fluid volume leads to joint problems. A disease associated with an increase in synovium is called “synovitis”. Synovitis is difficult to treat and requires long-term and patient treatment.

There are pathologies directly related to a lack of synovium, which also affects human mobility. For a patient who wants to figure out how to treat fluid in the knee joint, it is necessary to find out the causes of deviations, find effective ways therapy and pay attention to preventive measures.

Why fluid accumulates in the knee, symptoms

In fact, there are many factors that can cause effusion. Post-traumatic and infectious causes are common. The accumulation of fluid in the joint can also be observed as a consequence of an existing chronic disease.

Although it is difficult to list all the factors that can cause the development of synovitis, several main reasons can be identified:

The first signs indicating the presence pathological changes, is:

Swelling - compared to a healthy knee, there is a noticeable difference in the tissues of the kneecap.
Pain syndrome. A small amount of liquid has virtually no effect on the patient’s well-being. A large volume of effusion leads to severe pain. The patient is unable to stand straight, and often cannot even get to his feet.
Stiffness. Excess effusion leads to immobility of the knee joint. Often the patient experiences severe swelling, which prevents the leg from being fully extended.

You should consult a doctor if treatment with folk remedies does not bring visible results. Effusion often causes immobility, and infection that enters the cavity destroys the joint.

How to carry out the pumping procedure

There are two main ways to perform surgical drainage of joint effusion. Each method has its own characteristics.

Arthrocentesis. The surgeon removes the fluid using a syringe. Immediately after the procedure is completed, a corticosteroid hormone is injected into the synovial cavity to suppress the inflammatory process.
Arthroscopy. To gain access to the joint cavity, the surgeon makes several incisions in the skin through which a camera and surgical instruments are inserted. It is easier to get rid of fluid this way, and the recovery process is faster.

There are situations when fluid accumulates after surgery, in which case a repeat aspiration procedure is performed, with the obligatory introduction of antibiotics and hormonal drugs into the cavity.

If fluid from the knee joint is not drained in a timely manner, more serious measures will be required. One of the consequences of prolonged pathology is surgical replacement cartilage tissue or the entire knee.

Is it painful to pump out joint fluid?

Some patients avoid suction because they have heard that the procedure is painful. Is this really true? Not really. If synovial fluid collects in the knee joint and there is no help traditional methods therapy, therapy the only way it is possible to eliminate swelling and get rid of the pain syndrome accompanying synovitis only after pumping out the effusion.

During the procedure itself, the patient does not experience pain. To be fair, it should be noted that unpleasant tugging feelings are often observed.

What to do if there is not enough fluid in the knee

Lack of fluid in the knee usually occurs after a knee injury and surgery. In a normal state, the body is able to replenish the required volume and maintain it. There are two ways to restore joint fluid:

Injections hyaluronic acid. The introduction of the drug into the joint cavity leads to the creation of a microprosthesis - a partition that helps reduce friction between the cartilages. The drug simultaneously reduces swelling.
Ointments. Restoring fluid levels is also replenished with formulations based on hyaluronic acid. Less effective than injection. Unlike injections, you can apply the ointment yourself.

The effect of the drugs after a course of treatment lasts about 6 months.

Preventing knee problems

First of all, the attending physician is required to eliminate the causes of the appearance and accumulation of fluid. In some cases, drainage of the effusion may be necessary.

Prevention may include necessary physical exercise. The patient may be required to follow a special diet. Weight loss for obesity, best prevention synovitis

The fluid in the knee joint (other names: synovium, synovial fluid) is a thick elastic mass that fills the joint cavity. This is a kind of joint lubricant that performs a shock-absorbing function: it prevents friction of articulating articular surfaces, protects articular structures from wear, and provides nutrition to the cartilage and metabolism with it.

This fluid is produced by the epithelial cells of the synovium of the joint capsule. Normally, its content does not exceed 2–3 ml.

Excessive production of synovial fluid (also called “effusion”) is not a separate disease; this is just one of the manifestations of injury or inflammation (synovial bursa or other element of the knee joint).

Due to injuries, acute synovitis, bursitis and other inflammatory diseases, less often due to an allergic reaction to certain type allergens - the production of synovium increases, it accumulates in the synovial cavity, accompanied by local swelling, pain and other symptoms.

Depending on the cause of its excessive production, the composition of the liquid changes. It could be:

transparent (serous),
with an admixture of fibrin flakes (fibrinous),
pus (purulent),
blood (hemorrhagic).

The knee is one of the largest supporting joints, so it is more susceptible to injury and overload than many others. The likelihood of accumulation of excess fluid in its joint cavity due to similar reasons is higher than, for example, in the ankle, shoulder or small joints.

The patient's quality of life varies in relation to the severity of the underlying disease or injury. Excess synovial fluid plus inflammation leads to limitation of movements in damaged joint, affecting motor activity. It is also possible that the pain may intensify when walking and even occur at rest when standing while supporting the affected leg.

Treatment of pathologies and injuries that lead to excess effusion is carried out by a traumatologist, rheumatologist, arthrologist or surgeon.

Regardless of the root cause of the disease, it is important to begin treatment as early as possible. Otherwise, irreversible changes in the cartilage tissue and synovium may develop, which will inevitably lead to impaired motor function of the leg. With purulent inflammation, the development of life-threatening sepsis cannot be ruled out.

Causes of increased formation of synovial fluid

Excessive effusion can be a sign of many diseases and conditions. The table lists specific types of injuries and illnesses that can lead to this problem:

Group of reasons	Specific types of illnesses and injuries
Injuries: falling to the knee, blow, landing on your feet from a great height	Fracture of articular bones (femur or tibia in the area of the knee joint, patella);
	Capsules or bundles
	Hemarthrosis
Inflammatory and degenerative-dystrophic diseases of the joints

	Arthritis: rheumatoid, septic, gouty and other types
	Baker's cyst
	Pseudogout
	Rheumatism
	Gonarthrosis
	Koenig's disease
Other diseases and conditions	Allergic reaction
	Viral infections

	Hemophilia (a rare pathology associated with a disorder of blood clotting)

Synovitis of the knee - inflammation of the synovial membrane of the joint - one of the reasons for the increased production of synovial fluid

Risk factors

Hereditary predisposition to the occurrence of joint pathologies,
old age,
obesity,
sports,
heavy (unfavorable for joints) physical work.

Characteristic symptoms

Fluid in the knee joint begins to be actively produced not immediately after an injury or the onset of inflammation, but after some time. Symptoms vary in each case depending on the specific cause, but there are general signs, the intensity of which may be different for each patient:

swelling and swelling of the knee joint,
pain syndrome,
overflow of skin with blood at the site of joint damage or inflammation,
local temperature rise,
hemorrhage under the skin or into the joint cavity;
restriction of movement in the knee.

More about pain

An acute inflammatory process (arthritis) in the knee joint is always accompanied by severe pain, the intensity of which increases when you touch or move the leg. Chronic arthritis is manifested by a pain syndrome of moderate intensity: often the pain has a wave-like character with periods of subsidence and resumption.

Purulent synovitis is characterized by throbbing pain and a feeling of fullness from inside the affected knee joint.

Often the patient’s condition worsens due to the addition of symptoms of general intoxication.

About swelling

The degree of swelling varies from mild swelling to sharp increase volume of the knee joint.

With swelling, the shape of the knee joint is deformed; the articular capsule, stretched due to the accumulation of a large amount of effusion, can come out on the sides of the kneecap. Swelling around the patella is visually noticeable. Upon palpation, the doctor identifies signs of fluctuation—excessive accumulation of fluid in the cavity bounded by the synovial membrane. The greater the volume of accumulated effusion, the greater the limitation of knee functions.

What happens during injuries

At severe bruise first there is swelling, severe pain at rest and with movement, redness of the skin, formation subcutaneous hematoma. On the second or third day, excess fluid begins to accumulate in the knee joint.

When bones are fractured with rupture of blood vessels, blood flows into the joint cavity, and hemarthrosis develops. In this case, acute throbbing pain intensifies when attempting any movement in the knee.

Diagnostic methods

When diagnosing, the doctor is faced with the task of determining the cause of excess production of joint fluid.

“Manual” examination for the presence of excess fluid in the joint cavity: when pressing on kneecap it “sinks” into the bone all the way, and when you release your hands, it “floats up”.

Other diagnostic methods:

(if the table is not completely visible, scroll to the right)

Instrumental diagnostic methods without intervention in the patient's body	Diagnostic studies with intervention in the body
X-ray of the knee joint	Arthroscopy
Ultrasound of the knee	Arthrocentesis - puncture of the joint capsule with suction of fluid for examination
CT or MRI (if necessary)	Biopsy of the synovial membrane (if indicated) for its examination
Pneumoarthrography: oxygen, carbon dioxide or atmospheric air is injected into the joint, and then a series of x-rays. This diagnostic method is prescribed when the radiograph is insufficiently informative.

Treatment methods

As such, treatment of excess synovial fluid production is primarily treatment of the underlying disease.

General approximate scheme of conservative treatment

(if the table is not completely visible, scroll to the right)

Surgical intervention

Serious comminuted fractures of the knee joint bones or diseases that cannot be treated conservative treatment, require surgical intervention. Fluid in the knee is removed during arthroscopy. Also, effusion is pumped out from the joint cavity using a needle. To eliminate inflammation, after pumping, an antibiotic or hormonal agent is injected into the joint through the same needle.

In case of injury, it is possible to open the cavity of the knee joint in order to remove bone fragments and foreign bodies.
For chronic synovitis, partial or complete synovectomy is indicated - excision of part or all of the synovial membrane.
If there is significant wear of the articular elements, the last chance to avoid immobilization is endoprosthetics.

Resume

Today, a sufficient number of methods have been developed for pumping out excess joint fluid, but remember that this is only a manifestation of the underlying disease, timely treatment which will help prevent the activation of effusion production. It is impossible to eliminate the root cause only by removing synovial fluid - the fluid will continue to accumulate again.
