Endorsed by professional athletes, this brace is engineered to support recovery and enhance knee function during high-impact activities. ## 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: Absolute worth the money!! lifesaver when you need to walk before surgery - This is such a great knee brace . I wore it on my knee when I went to Europe . I walked in Italy , Croatia and Ireland. It really protected my knee and felt such great support. I had to have a knee replacement when I got back home from vacation I would not have been able to endure the trip without this knee brace !! Review: Brace - I shredded my knee a year ago and it is continuing to heal. I’m not sure it will ever heal completely. I ripped the kneecap right off sideways and everything that was holding it was torn. The knee literally went backwards 4 inches. That is the wrong direction to be going backwards! An orthopedic surgeon gave me this brace and it has been by far the best brace I’ve used. Due to the very high price, I have attempted to use at least 20 different styles of braces since. That has been a huge waste of time and money. And in the end, I lost my original brace on a trip. And I’ve ended up ordering two more of these $80 braces. The price is absolutely ridiculous and I feel taken advantage of by the price. But I love these braces. They make me feel more stable than any other others. I highly recommend this lightweight brace. It keeps my kneecap in the spot where it needs to be, and the height of the brace makes my leg feel much more stable. When my knee was at its worst in the beginning this was not nearly enough support by itself. I think I was on crutches for about nine months. The brace rolls up compactly for storage or travel. I washed this in the washing machine all of the time and hang it to dry. ## Features - Made of 60% polyester, 20% nylon, and 20% spandex, the undersleeve reduces friction or chaffing. The undersleeve is supposed to fit tightly, but if you’d prefer a larger undersleeve or need a replacement you can purchase a Reaction - Innovative web design absorbs shock, disperses energy and shifts pain away from your knee. Open webbing framework coupled with the mesh backing creates a comfortable fit and a breathable solution - Webbing acts to dynamically stabilize the patella (kneecap) on all sides, bringing the patella into proper tracking position to reduce pain. Designed to prevent injuries during high-risk activities, like sports. - Lightweight design makes this knee brace ideal for all-day use. This knee brace for men and women restricts knee movement to allow healing after surgery or injury. - Universal fit allows the DonJoy Reaction WEB Knee Brace to be worn on either the left or the right leg. Fit tip-circumference measurements should be taken at knee center 6 inch above and below the knee center ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NOW68CK | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #56,354 in Health & Household ( See Top 100 in Health & Household ) #241 in Knee Braces | | Brand | DonJoy | | Brand Name | DonJoy | | Closure Type | Hook & Loop | | Color | Blue | | Customer Reviews | 3.8 out of 5 stars 2,265 Reviews | | Item Dimensions | 13 x 1 x 10 inches | | Manufacturer | DJO Consumer LLC | | Material | Nylon, Spandex | | Model Number | DJ141KB01-BLU-M/L | | Number of Items | 1 | | Part Number | DJ141KB01-BLU-M/L | | Size | Medium/Large | | Special Features | Lightweight | | Specific Uses For Product | Patella Tendonitis, Osgood-Schlatter, Patellofemoral Tracking Issues, Mild OA, Chondromalacia | | Sport Type | Football | | Target Use Body Part | Knee | | UPC | 637801209587 888912054928 785923092607 812082807145 | | Unit Count | 1 Count | | Use for | Knee | ## Product Details - **Age Range (Description):** Adult - **Brand:** DonJoy - **Size:** Medium/Large - **Specific Uses For Product:** Patella Tendonitis, Osgood-Schlatter, Patellofemoral Tracking Issues, Mild OA, Chondromalacia - **Use for:** Knee ## Images ![DonJoy Reaction Web Knee Support Brace with Compression Undersleeve, Absorbs Shock to Relive Pain - Blue, Medium/Large - Image 1](https://m.media-amazon.com/images/I/61zFaEvVlkL.jpg) ![DonJoy Reaction Web Knee Support Brace with Compression Undersleeve, Absorbs Shock to Relive Pain - Blue, Medium/Large - Image 2](https://m.media-amazon.com/images/I/419rwKlSESL.jpg) ![DonJoy Reaction Web Knee Support Brace with Compression Undersleeve, Absorbs Shock to Relive Pain - Blue, Medium/Large - Image 3](https://m.media-amazon.com/images/I/61WjHAD-Q6L.jpg) ![DonJoy Reaction Web Knee Support Brace with Compression Undersleeve, Absorbs Shock to Relive Pain - Blue, Medium/Large - Image 4](https://m.media-amazon.com/images/I/61Wa6HFGoDL.jpg) ![DonJoy Reaction Web Knee Support Brace with Compression Undersleeve, Absorbs Shock to Relive Pain - Blue, Medium/Large - Image 5](https://m.media-amazon.com/images/I/41+azN3286L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Absolute worth the money!! lifesaver when you need to walk before surgery *by D***D on April 3, 2026* This is such a great knee brace .

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. ## 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/13760404-donjoy-reaction-web-knee-support-brace-with-compression-undersleeve-absorbs](https://www.desertcart.co.uk/products/13760404-donjoy-reaction-web-knee-support-brace-with-compression-undersleeve-absorbs) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
