Features

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