The DonJoy Reaction Knee Brace has been developed by an orthopedic surgeon for patients with Anterior Knee Pain.

Features & Benefits :

Progressive Pain Relief

  • Elastomeric web design creates energy dispersion across the knee for shock absorption, shifting the peak loads away from the painful area of the knee.
  • The Dual-axis hinges are flexible, creating synergy with the elastomeric web for optimal fit and support.

Sustained Comfort

  • The light weight, open framework of the elastomeric web in combination with the mesh backing create a very comfortable and breathable solution for anterior knee pain.
  • Integrated adjustment controls – no separate tools to keep track of

Stays in Place

  • The adjustable strapping at top and bottom allows uniform pressure across the knee working in tandem with elastomeric web to stay in place on the knee for all day usage.
