• Supplement Your Joints. ...

What is normal synovial fluid?

Normal synovial fluid is straw-colored, clear, and slightly sticky or stringy. Abnormal synovial fluid may be cloudy and thicker or thinner than normal fluid. Cloudiness could mean there are crystals, excess white blood cells, or microorganisms in the fluid. If you have gout, the fluid will contain crystals.

What are the functions of synovial fluid?

Synovial fluid has three functions inside the joint:

• It allows the ends of the bones to move without friction and lubricates the joint.
• It contains nutrients needed for the cartilage at the ends of the bones and carries away waste.
• It acts as a shock absorber.

How do you interpret synovial fluid results?

Synovial fluid should be viscous, meaning that it is thick and sticky. Synovial fluid that is an abnormal color can indicate inflammation. Synovial fluid is usually clear and colorless, but abnormal fluid can appear cloudy and colored. This suggests that microscopic or chemical changes have occurred.

How would you describe synovial fluid?

Synovial fluid, also known as joint fluid, is a thick liquid located between your joints. The fluid cushions the ends of bones and reduces friction when you move your joints. A synovial fluid analysis is a group of tests that checks for disorders that affect the joints.

What is synovial fluid made of?

Synovial fluid is produced as an ultrafiltrate of blood plasma and is primarily composed of hyaluronan, lubricin, proteinase, collagenases, and prostaglandins. [1] Synovial fluid production is from fibroblast like type B synovial cells.

Can synovial fluid leak from a joint?

When effusion happens in a joint — commonly the knee — excess fluid can pool in a part of the joint called the synovial cavity. It then leaks out into the soft tissue around the joint.

What is it called when you take fluid out of a joint?

This process of removing fluid from a joint is called arthrocentesis. Your doctor will send the fluid sample to the laboratory for examination.

What is the test for mucin clot?

Another test known as the mucin clot test (acetic acid is added to synovial fluid) estimates the production of hyaluronate. Poor mucin clot formation is associated with inflammatory types of arthritis. Blood tests or other laboratory tests can also be ordered with the intent of supporting the evidence derived from the synovial fluid analysis.

What is the procedure to draw synovial fluid from the affected joint?

Sterile technique must be followed when obtaining synovial fluid for analysis. Precautions are taken so that bacteria are not introduced into the joint.

What is the concentration of hyaluronic acid in synovial fluid?

Hyaluronic acid is synthesized by fibroblast-like synovial lining cells, and it appears in high concentrations in synovial fluid, at around 3 g/L, compared with a plasma concentration of 30 µg/L. Lubricin, a glycoprotein that assists articular lubrication, is another constituent of synovial fluid that is generated by the lining cells. It is now believed that hyaluronan functions in fluid-film lubrication, whereas lubricin is the true boundary lubricant in synovial fluid (see following). Because the volume of synovial fluid is determined by the amount of hyaluronan, water retention seems to be the major function of this large molecule. 234,238

What makes synovial fluid viscous?

Synovial fluid contains hyaluronic acid, which makes it very viscous. A small amount (pinch) of hyaluronidase powder should be added to all joint fluids to make them less viscous (liquefy them) before cell counts are performed by automated methods or manual methods or cytocentrifuge slides are prepared.

What is the function of synovial fluid?

Synovial Fluid. Synovial fluid, present in very small quantities in normal synovial joints, has two functions: lubrication and nutrition.62,63 Synovial fluid is a combination of a filtrate of plasma that enters the joint space from the subsynovial capillaries and hyaluronic acid, which is secreted by the synoviocytes.

What is synovial fluid?

Synovial fluid is both a lubricant for joint surfaces (lubricin for boundary cartilage-to-cartilage lubrication and hyaluronate for synovium-on-synovium lubrication) and a source of nourishment for the avascular articular cartilage. It also contributes to joint stability by forming a hydraulic “adhesive seal” between the two articulating bones.

How is synovial fluid cleared?

Synovial fluid is cleared through lymphatics in the synovium, assisted by joint movement. In contrast to ultrafiltration, lymphatic clearance of solutes is independent of molecular size. In addition, constituents of synovial fluid, such as regulatory peptides, may be degraded locally by enzymes, and low-molecular-weight metabolites may diffuse along concentration gradients into plasma. The kinetics of delivery and removal of a protein must be determined (e.g., using albumin as a reference solute) to assess the significance of its concentration in the joint. 237

What are the elements that are absent from synovial fluid?

Notably absent from synovial fluid are elements of the coagulation pathway (fibrinogen, prothrombin, factors V and VII, tissue thromboplastin, and antithrombin). 65 As a result, normal synovial fluid is resistant to clotting.

Where is synovial fluid found?

Synovial fluid is normally present in very small amounts in the synovial cavity surrounding joints. When fluid is present in amounts large enough to aspirate, there is a disease process in the joint.
