## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ UPDATED:Amazon resolved the confusion over the brace and I have faith in them again
*by M***K on March 13, 2024*

UPDATE:I did resolve the issue with Amazon and my surgeon ended up ordering me this brace for me and it was sold by the manufacturer and will hopefully be covered by my insurance company. I did get the next size up and now the hinges actually work (they couldn’t work with the brace from Amazon being too small).I don’t know how well this brace works for other issues, but the issue causing my pain is patellar maltracking which has developed over the years into arthritis. I first began having knee pain in 2016, I guess. I would think it would help with anything requiring kneecap support. It is the only brace that is able to give me pain relief and fits my kneecap.The biggest issue I see is that the size chart is not the same as on the manufacturer’s website. The manufacturer advised me to order one from them but they are more expensive. They then said to at least use their size chart if I order from Amazon. I will likely order from somewhere else altogether as Amazon seems to be telling me they are giving me a refund and it is not appearing. There was some confusion on my part about whether or not it fit after they initially refunded my money when it didn’t seem to fit and hurt as part of it digs into my knee. So I then tried using the sleeve and it helped with the pain from the brace so I thought since it was supporting my kneecap it fit me. I actually asked Amazon to charge me again as I didn’t want to use the brace after getting a refund being that it is so expensive. But I realized that the hinges need to be on the sides of my knee and instead they are just beside the kneecap and my legs are wider than a medium/large, so the hinges are not on the side of my knee. I then asked for the money back again and now I guess Amazon thinks I am changing my mind too much and I think the real issue is that they need to have the correct sizing information in the pictures. I would not recommend anyone buy this unless they check the manufacturer’s website first.

### ⭐ 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 offI 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.

### ⭐⭐⭐⭐⭐ supportive and able to still have movement.
*by A***N on March 24, 2025*

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.
