Synovitis can be cured with surgery. Synovitis occurs when the synovial membrane in the joint cavity is subjected to mechanical, biological, chemical, and immune factors that cause synovial membrane proliferation and synovial fluid production. Synovitis is caused by pathological damage to the synovial membrane, and after surgery, the synovial membrane can be completely removed from the synovial membrane and the diseased synovial membrane. Therefore, synovitis can be completely cured after surgery because no symptoms can be produced after the lesion is completely removed, so no pain or synovial fluid can be produced.
