 Knee Brace -Reaction

 The REACTION knee brace is a responsive, webbed approach to anterior knee pain that gives a distinct alternative to the basic knee sleeve.

 The DonJoy Reaction knee brace utilizes an elastomeric web design, which absorbs shock and shifts the peak loads away from the painful area of the knee. This dispersion of energy helps reduce the anterior knee pain.

TheDonJoy Reaction knee brace has a  web design which dynamically stabilizes the patella on all sides, thus bringing the patella into proper tracking position to reduce pain caused by general patellofemoral instabilities.
The DonJoy Reaction knee brace is extremely comfortable to wear because of this unique design which is also brace breathable, unlike the traditional elastic and neoprene sleeves.

The DonJoy Reaction knee brace is used to treat or prevent the following injuries:

  • Chondromalacia patella
  • Quadriceps or patellar tendonitis/tendinosis
  • Osgood-Schlatter disease
  • General patellofemoral tracking issues
  • Mild OA


  • Progressive Pain Relief The web absorbs shock and shifts the peak loads away from the painful area of the knee and stabilizes the patella on all sides to ensure proper tracking position.
  • Sustained Comfort The open framework and mesh backing makes this brace breathable and comfortable during use.
  • Dual-Axis Hinges These hinges are flexible and work in conjunction with the elastomeric web for optimal fit and support, and providing energy dispersion to the knee.
  • Reduces anterior knee pain by dispersing energy across the knee.
  • A New innovative solution that disperses knee pain!
