Patients with advanced joint deformity, ankylosis, or loss of function that cannot be reversed or improved by medications should be actively considered for orthopedic surgical treatment. Surgery plays an important role in the treatment of patients with severely diseased joints. Although arthroplasty and total joint replacement can be performed on most joints, the most successful surgeries are performed on the hip and knee. The practical goals of these surgeries are to reduce pain to correct the deformity and to improve function as appropriate. Reconstructive surgery results in improved appearance and improved function. Open or arthroscopic synovectomy may be helpful in some patients, especially those with persistent unicompartmental knee arthritis. In addition, early synovectomy of the carpal tendon may prevent tendon rupture. Preventive and Nursing Measures 1). Prevent sweating as wind and getting cold, do not be in a humid environment for a long time, and prevent the invasion of wind, cold, dampness and other evils. 2). Keep optimistic spirit, avoid emotional stimulation, and pay attention to psychological therapy. 3). When the disease is stabilized, go outdoors more often and insist on functional joint exercises to maintain and improve the joint function and improve the quality of life. 4). Strengthen the nutrition, enhance the disease-resistant ability, and prevent the disease from recurring or deteriorating.
