The DonJoy REACTION Knee Brace features a patented elastomeric web design with dual-axis hinges that dynamically stabilize the patella, dispersing shock and reducing knee pain.

## Description

Product Description The DonJoy Reaction WEB Knee Brace uses a responsive, webbed approach to knee pain that gives you a distinct alternative to the basic knee sleeve. Developed by world renowned orthopedic surgeon, Dr. William Nordt, the DonJoy Reaction WEB can help decrease knee pain and increase function, getting you back to your active lifestyle. The elastomeric web is an innovative solution that absorbs shock, disperses energy and shifts pain away from your knee. This webbing acts to dynamically stabilize the patella (kneecap) on all sides, bringing the patella into proper tracking position to reduce pain. The open framework of the elastomeric web, in combination with the mesh backing, creates a comfortable fit and a breathable solution for relief of anterior knee pain. It's secured with Velcro straps, and weighs only 0.5 lbs. The lightweight design makes this knee brace ideal for all-day use. One undersleeve is included, and is made of 85% nylon/15% spandex. The DonJoy Reaction WEB can be used to treat or prevent the following knee injuries: patellofemoral pain syndrome (PFPS), chondromalacia patella (runner’s knee), quadriceps or patellar tendonitis/tendinosis (jumper’s knee), Osgood-Schlatter disease, general patellar tracking issues and instability, and mild knee osteoarthritis. The DonJoy Reaction WEB is worn by professional snowboarders, volleyball, football players; as well as the U.S. Snowboarding and U.S. Ski teams. Universal fit allows the DonJoy Reaction WEB Knee Brace to be worn on either the left or the right leg. Indications Chondromalacia patella. Tendonitis of the Quadriceps and/or Patella. Poor patella tracking. Patellofemoral pain. Mild OA (osteoarthritis). Mild Osgood-Schlatter Disease.

## Features

- Progressive Pain Relief — The elastomeric web design helps to reduce pain by dispersing energy across the knee. The web acts like a spring to absorb shock and shifts the peak loads away from the painful area of the knee.
- Elastomeric Web — Acts to dynamically stabilize the patella on all sides, bringing the patella into proper tracking position to reduce pain for patients with general patellofemoral instabilities.
- Reimbursable Solution — PDAC-assigned code for L1810, the REACTION WEB has dual-axis hinges that are flexible, creating synergy with the elastomeric web for optimal fit and support, and providing energy dispersion to the knee.
- Sustained Comfort — The open framework of the elastomeric web, in combination with the mesh backing, creates a comfortable fit and a breathable solution for relief of anterior knee pain.
- Stays in Place — The adjustable strapping at the top and bottom allow uniform pressure across the knee working in tandem with the elastomeric web to stay in place on the knee for all-day usage.
- Better Fit and Comfort — A new back pad fits and conforms better to the knee, and is softer, more breathable and more lightweight.
