Undifferentiated osteoarthritis can now be treated with medication, physical therapy, and surgery to relieve symptoms. 1. Medication: If the joints are swollen and painful due to undifferentiated osteoarthritis and cannot move normally, oral non-steroidal anti-inflammatory drugs can be taken to relieve the pain, such as celecoxib and indomethacin. 2. Physiotherapy: For example, traction therapy, infrared physiotherapy, baked electricity physiotherapy, etc., which can accelerate blood circulation and achieve pain relief and anti-inflammatory purposes. 3. Surgery: mainly for the more serious undifferentiated osteoarthritis, arthroscopic cleanup, joint replacement, joint fusion can be used to achieve the therapeutic purpose. Undifferentiated osteoarthritis should be treated as early as possible to avoid delaying the condition and causing damage to the surrounding bone joints and soft tissues.
