Endorsed by professional athletes, this brace is a top choice for managing patellofemoral pain and related knee conditions. ## 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.

Daughter absolutely loves it for support while horseback riding for her torn ACL. Light and easy to adjust. Bought without the sleeve as she wears it over her leggings or her copper compression sleeve during basketball. Sizing is as shown in the chart. Her measurements matched fit perfectly. ## Frequently Bought Together - DonJoy Reaction Web Knee Support Brace with Compression Undersleeve: Blue, Medium/Large - DonJoy Reaction Compression Support: Knee Brace Undersleeve, Medium - DonJoy Knee Brace Undersleeve, Closed Patella, Medium --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/367965013-donjoy-reaction-web-knee-support-brace-with-compression-undersleeve-blue](https://www.desertcart.co.uk/products/367965013-donjoy-reaction-web-knee-support-brace-with-compression-undersleeve-blue) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-14*
