How to differentiate knee synovitis from rheumatoid arthritis

There are clear differences between knee synovitis and cold-damp arthritis in terms of causes, symptoms, and treatment methods: 1. **Causes**: Knee synovitis is often caused by knee joint sprains, infections, obesity, injuries, and other factors leading to inflammatory reactions in the synovial membrane. Cold-damp arthritis, on the other hand, is primarily caused by cold and dampness invading the joints, and may be related to genetic factors, infections, immune responses, and more. 2. **Symptoms**: Knee synovitis is characterized by symptoms such as swelling, pain, and localized warmth in the knee joint, with possible limitation of movement in severe cases. Cold-damp arthritis mainly presents with joint pain, swelling, morning stiffness, and may also be accompanied by joint deformities. 3. **Treatment**: Treatment for knee synovitis includes medication, physical therapy, and surgical treatment, among others. Treatment for cold-damp arthritis involves various methods such as moxibustion, cupping therapy, and topical application of traditional Chinese medicine.
