In general, due to the early attack on cartilage, rheumatoid arthritis is mainly characterized by narrowing of the joint space, osteoporosis around the joint, and swelling of the soft tissue around the joint. Osteomalacia is a later development. In addition to medical medication, early surgical intervention can reduce the damage to the joints caused by this disease, while removing a large amount of synovial membrane and taking out the basis of the disease’s pathogenesis can contribute to drug control. The synovial membrane of the knee joint accounts for 50% of the total synovial membrane of the body, and arthroscopic synovectomy is beneficial for the relief of knee symptoms as well as for the control of lesions in other parts of the body.
