 Medical specifications

4-point rigid brace for treating injuries of the posterior cruciate ligament

M.4s PCL dynamic is a functional knee orthosis. The product allows the conservative or postoperative treatment of patients with a (partial) rupture of the posterior cruciate ligament.


Product benefits

  • By actively exerting a force via the PCL protection pad the tibia is holding in the desired position

  • Safe collateral stabilisation by rigid frame

  • Extension and flexion limitation protects against damaging joint movements and relieves injured structures

  • Optimal imitation of knee movement by using patented physioglide Hinge Technology

  • Limitations:

  • - Extension limitation: 0°, 10°, 20°, 30°, 45°

  • - Flexion limitation: 0°, 10°, 20°, 30°, 45°, 60°, 75°, 90°

  • - Immobilisation: 0°, 10°, 20°, 30°, 45°

Wearing directions

Only change the extension and flexion limits on instruction from your doctor or orthotist. In order to prevent hyperextension, always insert extension wedges or 0° wedges. The wedges define the exact excursion of the orthosis. In difficult soft-tissue conditions, e.g. where the soft-tissues are under compression, it may be necessary to insert the larger wedge to limit the joint movement to the desired excursion. In addition, make sure that the orthosis joints are correctly positioned: the middles of the joints should be level with the upper border of the patella. The joint must lie behind the midline of the leg.
