DonJoy Reaction Knee Brace Overview
The DonJoy Reaction Web Knee Brace, designed by world-renowned orthopedic surgeon Dr. William Nordt, uses a webbed approach to respond to knee instability and pain. The elastomeric web has a spring-like structure that distributes energy and absorbs shock to shift pain away from the knee. The mesh backing and open web framework provide a breathable, comfortable solution for relieving anterior knee pain. Adjustable straps apply uniform pressure and work with the elastomeric web to keep the knee brace securely in place. This lightweight brace support weighs only a half pound, allowing for comfortable all-day wear during activities like soccer, basketball, walking, and more.

DJO Reaction Knee Brace's Elastomeric Web Design
The open, breathable webbed front design stabilizes the patella by bringing it to its proper tracking position. It also disperses energy across the knee and absorbs shock. This increased stability and shock absorption efficiently reduce pain for individuals with patellofemoral conditions.
Flexible hinges on each side of the DonJoy Reaction Brace provide additional support to the knee. When paired with the elastomeric web, the dual hinges create an optimal fit and aid with energy dispersion to the knee. The dual-axis hinges help absorb shock and offload weight away from the painful area of the knee.
