Features + Benefits

  • Adjuster technology
    Provides the highest average amount of condylar separation. (Komistek Study—head-to-head comparisons of commercially available OTS OA knee braces.)
  • Lightweight and tough
    The combination of the durability of aluminium and leveraging the strength of nano MAG™ make it lightweight and tough
  • Functional comfort
    Sleek design combines a new calf contour design and an evolution in nano MAG material science
  • Clinically-proven*
    DonJoy’s Adjuster™ Technology offloads a little – or a lot – and nano MAG Technology on the offloading side provides lightweight function with the strength of aircraft-grade aluminum. Floating hinges allow a contoured, personalized fit for all levels of activity.
  • 4 points of leverage™ system
    Pioneered by DonJoy, it provides clinically proven ligament stability* with:
    1. Anterior Thigh Anchor
    2. Posterior Tibia Anchor
    3. Lower Thigh Strap Pushes Femur Anteriorly
    4. Anterior Tibia Strap Applies An Active Constant Load To Prevent Anterior Tibial Translation
  • Contoured calf cuff
    The posterior calf cuff is contoured to enhance overall brace suspension for various levels of activity and it is designed to fit a variety of body shapes and sizes.
  • Anti-migration band & strap pads
    Included in the accessory bag for additional brace customization. With significant weight reduction, internally mounted strap tabs and a contoured calf cuff, OA Adjuster 3 is engineered to stay in place
