The M.3 OA osteoarthritis knee brace utilizes a single upright strut and incorporates medi’s patented varus/valgus loading mechanism and Physioglide hinge to provide effective treatment for mild to moderate symptoms of uni-compartmental osteoarthritis. The unique flex-bar system allows the single upright strut to flex and provide effective pain relief and reduce point-loading pressure. The advantages of the flex-bar, loading mechanism and Physioglide hinge combine with the soft-grip padding system and numbered straps to provide exceptional patient satisfaction and high compliance. Additionally the M3OA comes as a varus/valgus brace which for example can be used as a right leg varus (medial) unloading brace or a left leg valgus (lateral) unloading brace. This feature reduces inventory demands and increases potential applications.


  • Patient adjustable off-loading for effective pain relief
  • Air/foam condylar pads for all day comfort
  • Malleable frame design is easy to fit and live with
  • Extension limitation at 0 degrees or 10 degrees for added stability as needed
  • 3 point principle system for effective off loading and pain relief
