DJO Reaction Knee Braces & Sleeves

Knee pain that flares during activity but eases at rest usually points to load — patellofemoral stress, mild instability, or the ache of tendinopathy. The DJO Reaction line answers that specific problem with its signature elastomeric web: a network of flexible bands that stretch under motion to absorb and redistribute force away from the joint, rather than simply squeezing it. That's the difference between managing symptoms and actually offloading the knee while you stay moving.

The DJO Reaction Knee Sleeve is the everyday choice for arthritis, runner's knee, and general anterior knee pain. It combines a pull-on fabric sleeve with the web technology and a hook-and-loop strap for fit fine-tuning, and it's built to fit either knee. Sizing runs by thigh-to-calf circumference from X-Small/Small (13–18.5") up through XXXL, so measuring around the leg — not guessing by clothing size — is the way to land the right one.

For patients needing more structure, the Reaction Knee Brace and Reaction WebHinged Knee Brace add hinged support for mild-to-moderate instability, meniscus recovery, or ligament reassurance during rehab. The web still does its shock-diffusing work; the hinges add lateral control and prevent hyperextension.

A common question: sleeve or brace? If you want warmth, compression, and pain relief for a stable knee, the sleeve is enough. If the knee feels loose, catches, or is recovering from injury, choose a hinged brace. Both are low-profile enough to wear under athletic pants without bulk.
