Arthritis bone erosion is clinically called erosive osteoarthritis and is considered to occur in the foot. Treatment includes medication, physical therapy and drug therapy. 1. Drug therapy: patients with obvious pain can take oral non-steroidal anti-inflammatory drugs, such as Loxoprofen sodium and Celecoxib capsules. When there is joint effusion, hormone therapy can also be injected into the joint cavity, and immunosuppressants, such as methotrexate and hydroxychloroquine solution can improve the condition. 2. Physical therapy: Physical methods such as electrotherapy, hydrotherapy and shock wave can be used to promote local blood circulation and speed up the recovery. 3. Surgery: If the erosive osteoarthritis of the foot is serious, surgical debridement can also be considered for lesion removal and bone grafting. If erosive osteoarthritis of the foot is diagnosed, it is recommended to carry out standardized treatment as early as possible to reduce the adverse effects of the disease. The above medications are recommended to be used under medical supervision.
