Evaluation of the Effects of Pulsed Electromagnetic Field on Inflammatory Knee Osteoarthritis

Brief Summary

This study will assess the efficacy of pulsed electromagnetic field therapy in patients with inflammatory knee osteoarthritis confirmed by MRI-detected effusion-synovitis. Fifty participants will be randomly allocated into two groups. One group will receive active PEMF therapy at a specific optimized parameter twice a week for 8 weeks, while the other group will receive sham treatment using the same device without PEMF signal. The primary outcome is the change in WOMAC pain score, and secondary outcomes include knee function, stiffness, quality of life, and MRI-quantified structural changes.
