Synovial thickening

Normal joint synovial fluid is alkaline fluid. Due to increased exudation after joint injury, acidic products accumulate in the joint, the synovial fluid becomes acidic, which promotes the precipitation of cellulose. If the fluid is not cleared in time, the joint synovial membrane will respond to long-term inflammation Promote the gradual thickening of the synovium, and fibrosis, causing adhesions and affecting the normal movement of the joints.
