M.4®s OA

4-point knee orthosis for control of anterior and posterior tibial translation.
3-point off-loader for varus or valgus pressure relief.

  1. conservative treatment of complex ligament instability, particularly in conservative treatment of advanced unilateral osteoarthritis
  2. post-operative pressure relief and compartmental protection after fractures of the tibial head, cartilage surgery, meniscus refixation, correction osteotomy
  3. instability of the cruciate ligaments with pressure relief of the medial or lateral compartment
  4. for functional pre- or post-operative care of knee instabilities
Mode of action
  1. Protection, stabilisation, pain relief and restoration of mobility
  2. pressure relief of the medial or lateral joint compartment by the 3-point principle which off-loads the affected compartment into a varus or valgus position
  3. stabilisation of the knee joint by the 4-point principle to counteract knee instablity, a cause of osteoarthritis.
  4. safeguards against hyperextension and offers limitation of flexion and extension
  1. 'S' profile improves torsional stability whilst following natural alignment of femur and tibia
  2. hinges proximal to knee joint allow precise off loading of the knee polycentric hinges
  3. anatomically premoulded frame
  4. strong, low profile, light weight frame and hinge construction
  5. numbered straps ensure a simple fastening sequence
  6. air condyle pads with skin-grip system
  7. excellent comfort with new soft-grip padding material
  8. extension limitation at: 0º, 10º, 20º, 30º, 45º
  9. flexion limitation at: 0º, 10º, 20º, 30º, 45º, 60º, 75º, 90º, 120º
  10. immobilisation at: 0º, 10º, 20º, 30º, 45º
  11. under sleeve and knee protector available
