Synovitis pellets do not completely cure synovitis, which is caused by excessive activity of the knee joint or excessive damage to the joint, resulting in the formation of a large amount of synovial fluid. When treating synovitis, you should limit the activities of the knee joint and avoid prolonged weight-bearing or activities of the knee joint. At the same time, you can give knee joint baking and moxibustion, and extract the joint fluid if necessary, which can prevent further swelling of the knee joint. If conservative treatment does not have any effect, surgical treatment can be used to remove the synovial membrane, which can achieve the purpose of radical treatment, generally every 3 days after surgery, the stitches are removed in 2 weeks to avoid excessive weight bearing or excessive strain on the knee joint, which can affect the recovery effect.
