What Is Flexor Synovitis?

Synovitis is a joint disease in which the synovium is stimulated to produce inflammation, which causes the secretion of fluid to become imbalanced. There are two common types of synovitis: non-specific synovitis and specific synovitis. The knee joint is the joint with the most synovium in the whole body, so the synovitis is more common in the knee joint. When the joint is affected by extrinsic and intrinsic factors, the synovium reacts, causing congestion or edema, and exuding fluid, which is manifested as joint swelling, pain, joint fluid accumulation, and restricted movement. If not treated in time, it will affect the normal movement of the joints and cause joint damage or even disease.
