## Overview

The DonJoy Reaction WEB Knee Support Brace features an innovative elastomeric web design that absorbs shock and stabilizes the patella dynamically. Crafted with breathable mesh and a snug nylon-spandex undersleeve, it offers lightweight, all-day comfort and universal fit for either leg. Clinically designed to reduce knee pain and prevent injuries during high-risk activities, it’s the go-to brace for professional athletes and active individuals seeking reliable knee protection and enhanced mobility.

## 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.

Review: Mosh Pit with a Torn Meniscus! - This brace is amazing, so much stabilization. Totally makes it possible for me to be active with a torn meniscus. Very easy to adjust to fit well and my knee joint is super supported. The on/off process is way better than the neoprene thing the doctor gave me. I survived a mosh pit with this thing aftera day of hiking and then ran around at the beach the next day— I would not have believed this was possible before. With this thing I feel like I can be active again without falling over in pain. I did have to put cushioned tape on one corner bc it was signing into my thigh a bit. This is prob bc I have heavier thighs than the athletes it was designed for. Minor addition fixed it though. Really thankful for this brace!
Review: supportive and able to still have movement. - My daughter is 11 and a gymnast. She started having and issue this year with Plica of her knee tendon and Hoffa -the swelling of the fat pad under the knee cap. This brace was super tight at first, but stretched a bit and my daughter feels supported and comfortable and her knee issue on one side has resolved.

### ⭐ Very uncomfortable
*by K***R on December 30, 2020*

I ordered this brace after having meniscus surgery on my knee 5 months ago. I was hoping it would provide support for me while trying to get back into activities like hiking, biking, and skiing. I measured my leg according to the instructions and ordered a size large. After the brace arrived, I tried it on with the compression sleeve. It was so tight that I could not wear it. I tried the brace without the sleeve and it fit ok. It has to be strapped on tight to work properly, which makes it less comfortable. I decided to try it on a mountain bike ride. I strapped it on and loaded my bike into my truck for a 15 minute drive to the trails. My leg was in pain by the time I arrived due to the brace. I rode around for about 2 minutes and the brace was very uncomfortable and did not perform as I was hoping. I took it off I think the problem is on the design. It seems like once the knee is flexed, it stretches the plastic until the knee is in the straight position. This does not allow partial flexion, which renders it useless for me and what I wanted to use it for. I ended up finding a better one made by 3m at my local cvs. I have worn it skiing multiple times and often forget it is there as it provides the support I want. I do not recommend this brace because in my opinion it is so uncomfortable that I do not want to wear it.
