M.4 X-lock knee brace

  • Waterproof pads for showering
  • Lock mechanism easy mobility
  • Prevents muscle atrophy


The M.4 X-lock is a 4 point brace with extension lock.It offers reliable locking when fully extended which results in axial loading in the extended position.The compression resulting from the pressure promotes the stability of the suture.The split cushions can be positioned to prevent pressure on the surgical suture.The reliable blocking when fully extended means that the patient can move freely without walking aids.

Product benefits:

  • Stabilisation of the knee joint via the 4-point-stabilisation-principle
  • Water-repellent padding material - brace can also be worn while shower.
  • The physioglide hinge mimics the roll-glide movement of the knee and supports secure fit on the leg.
  • The lock mechanism enables a quick change between immobilisation in extended position and free movement within a defined range of motion
  • The split strap pads (strap 4) can be positioned induvidually. This can prevent undesired pressure on operative incisions.
  • The movable D-rings adjust flexibly upon movement and provides that the brace supports secure fit on the leg
  • The extra extended calf shells provides an improved fit and counteracts potential pressure points.
  • Comprehensive set of wedges for flexible extension and flexion limitation
  • Anatomically pre-moulded frame
  • Numbered straps for easy and simple usage


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