Unique polycentric hinge design closely mimics the roll and glide motion of the knee

Product Description 

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

Features and Benefits

  • Reliable pressure relief from the 3-point principle with varus/valgus adjuster
  • S-shaped frame and floating flexible D-rings ensure a snug and comfortable fit
  • Innovative non-slip cushioning material for frame and strap pads achieve a greater degree of patient comfort and compliance while optimizing migration control
  • Patented flex bar allows transfer of force across the joint, removing pressure on affected compartment
  • Ultraflat, lightweight and low profile frame and hinge construction of Avional alloy material which is 30% more rigid than other aluminum alloy technologies of the same weight.

Indications (Conservative):

  • Moderate to severe medial or osteoarthritis combined with ligament instability
  • Strong overloading of the medial or lateral compartment
  • Unicompartmental relief before HTO (brace test)
  • For relief of severe, painful bone edema (bone bruising)
  • For relief of painful stress fractures

Indications (Postoperative):

  • Cartilage surgery
  • Chondroplasty
  • Meniscus refixation
  • Displacement osteotomy with required postoperative relief of the medial or lateral compartment

Mode of Action:

  • Protection, stabilization, pain relief and restoration of mobility
  • Pressure relief of the medial or lateral joint compartment by the 3-point principle which offloads the affected compartment into a varus or valgus position
  • Stabilization of the knee joint by the 4-point principle to counteract knee instability, a cause of osteoarthritis
  • Safeguards against hyperextension and offers limitation of flexion and extension


  • “S” profile improves torsional stability while following natural alignment of femur and tibia.
  • Hinges proximal to knee joint allow precise off loading of the knee
  • Polycentric hinges Anatomically premolded frame
  • Strong, low-profile, light-weight frame and hinge construction
  • Numbered straps ensure a simple fastening sequence
  • Air /foam condyle pads
  • Excellent comfort with new soft-grip padding material
  • Need for limitation of extension and flexion to protect against harmful joint movements and for reliable relief of stresses on injured structures
  • Extension limitation at: 0°, 10°
  • Optional ROM limitation at 20°, 30°, 40° available upon request.
  • Under sleeve available
