Osteoarthritis is a disease caused by degenerative changes in the joints, with symptoms primarily manifesting as swelling, pain, fluid accumulation, and limited mobility in the joints. Severe cases may even lead to joint deformities and movement disorders. In terms of treatment for arthritis, it can be divided into non-surgical and surgical treatments. Non-surgical treatment involves rest and avoiding strenuous activities to prevent further joint damage. It may also include the use of anti-inflammatory painkillers, chondroprotective drugs, or intra-articular injections of sodium hyaluronate to relieve symptoms. Additionally, treatments such as hot compresses and physical therapy can be used. When conservative treatment is ineffective or accompanied by limb deformities and movement disorders, joint replacement surgery may also be an option.
