DonJoy Reaction Web Knee Brace

Reduces anterior knee pain by dispersing energy across the knee.

The DonJoy Reaction Knee Brace is designed to treat or help prevent patellofemoral problems. It does this by absorbing shock to the knee and dispersing the energy away from the patella (kneecap). This considerably reduces pain felt in the front of the knee. It provides good support to the patella and some support for the knee in general.

The brace has an elastomeric web design with an open framework and mesh backing. This makes it very light (only half a pound), breathable, and comfortable to wear, and is therefore an excellent alternative to traditional neoprene or elastic sleeves. Lateral patella buttresses all around the knee maintain the kneecap in the correct tracking position while the dual-axis hinges, made from the same flexible plastic as the buttresses, protect the MCL.

The Reaction Knee Brace is constructed to help people with patellofemoral tracking problems; tendonitis or tendonosis in the patella or quadriceps; patellar subluxation; chondromalacia patella (runner’s knee); Osgood-Schlatter disease, and mild osteoarthritis.

For dislocated knees, other DonJoy braces to consider are the Tru-Pull Light or the Hinged Lateral J, which both have the lateral patella buttresses. The Reaction distributes more shock away from the patella, and is a more adjustable brace, than the Lateral J.

The Reaction is not the right brace for people with ACL or PCL knee injuries, who should take a look at braces designed specifically for those conditions.

It is, however, a good brace to consider if you suffer from any of the conditions listed above, but want to continue playing sports such as soccer, lacrosse, football, softball, running, tennis, and watersports. You can wear it for contact sports if you’re sure you don’t need more protection. There are no exposed metal parts that could potentially injure teammates or opponents.

For a sport like volleyball, where you might want to slide along the floor, wear a pad over the webbing to prevent the webbing sticking.

The brace, which can be worn on either leg, comes with one undersleeve, although the brace can be worn without it. For fashion conscious athletes, the Reaction brace is available in a variety of colors.

There can be a few issues with the durability of the brace when worn on a daily basis and subjected to heavy use. People have reported that the Velcro on the straps wears out more quickly than expected, that occasionally it doesn’t properly adhere to the brace material, and that the straps can suddenly come undone in the middle of activity. Other users have reported the rubber web snapping. Most people are extremely satisfied with the brace, but if your brace does develop a problem, it is covered by a warranty for the first six months.

The DonJoy Reaction knee brace utilizes an elastomeric web design, which absorbs shock and shifts the peak loads away from the painful area of the knee. This dispersion of energy helps reduce the anterior knee pain you suffer from.

Another advantage of the elastomeric web is it dynamically stabilizes the patella on all sides, thus bringing the patella into proper tracking position to reduce pain caused by general patellofemoral instabilities.

The DonJoy Reaction knee brace is extremely comfortable to wear because the open framework of the elastomeric web and mesh backing makes the brace breathable, unlike the traditional elastic and neoprene sleeves.

Please note: The Reaction Web knee brace does include the Under Sleeve shown in the picture. For a Replacement Under Sleeve, please do a search on our website for Donjoy Reaction Under Sleeve.
