Rheumatoid arthritis (RA) is a systemic autoimmune disease that is characterized by chronic synovial inflammation in the joints, which can lead to permanent joint cartilage and bone erosion and damage, followed by joint instability, destruction, joint pain and stiffness, resulting in impaired joint function. A multidisciplinary team of rheumatology, physiotherapy, orthopedics, occupational therapy, social work, podiatry and clinical psychology is currently advocated for the treatment of RA. Orthopedics plays an important role in the treatment of RA as one of the surgical treatments. The timing and means of surgical treatment should be selected appropriately according to the specific lesions of each individual. If, after 3-6 months of standardized and adequate medical treatment, the inflammatory manifestations of synovial joint swelling and pain are not significantly relieved, or if imaging shows early erosion of joint cartilage or bone, synovectomy can be considered. Synovectomy is most widely performed in the synovial-rich knee. Minimally invasive arthroscopic synovectomy is becoming increasingly popular. 2. Osteotomy: Patients with RA have abnormal lower extremity force lines, mostly knee valgus deformity, which can be corrected by osteotomy. However, osteotomy requires stable ligamentous tissue (collateral and cruciate ligaments) as a prerequisite. In the correction of forefoot deformity, osteotomy of the metatarsal bone is also feasible instead of metatarsal head resection. 3. Arthroplasty: For shoulder joint bursitis, orthopedic shoulder can be performed to relieve the pain. The most effective surgical treatment for elbow joint pain is radial head resection. Artificial joint replacement: Artificial joint replacement, especially knee and hip replacement, has become the gold standard for the treatment of advanced RA, with positive long-term follow-up results. Compared to osteoarthritis, the age indication for arthroplasty in RA patients is relatively broader, because RA patients are younger in age, have more severe joint deformities, and have a greater impact on function and quality of life. Arthroplasty plays an important role even in the treatment of juvenile RA. 5, joint fusion: With the maturity of artificial joint technology, the application of joint fusion in large joints is gradually decreasing, only as a remedy of last resort. However, fusion still plays an important role in RA cervical spine lesions and podiatry.
