Where Synovial Fluid Is Found

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.

Where does the fluid found within the synovial joint cavity come from?

Synovial fluid is produced by the synovium and coats the tendons in the tendon sheaths and the surface of the synovium in normal joints. Synovial fluid is cleared through the subintimal lymphatic vessels which are assisted by joint motion.
