Joint synovectomy is the surgical removal of the synovial membrane, the tissue that lines the joint capsule.

Synovium surrounds the body’s joints and produces synovial fluid to help lubricate the joint enabling smooth movement. In cases of joint disease, the synovium becomes inflamed (synovitis) and produces excess synovial fluid containing an enzyme that can eat away the cartilage on the joint surface leading to bone on bone joint pain.
