Fusion® OA Plus Osteoarthritis Knee Brace

Sizes X-Small, Small, Medium, Large, X-Large, XX-Large

The Fusion® OA Plus knee brace provides patients with medial compartment off-loading for unicompartmental osteoarthritis. It features Breg’s exclusive adjustable hinge technology, which provides an effective valgus load to the knee. The hinge utilizes Breg’s thumbwheel dial design that allows patients to easily adjust the level of offloading without using a tool. Breg’s ProForm™ technology provides an intimate, contoured fit, that keeps the brace in place all day long. Fusion® OA Plus provides medial / lateral, anterior / posterior stabilization and support.

Fusion OA Plus Knee Brace Innovation

With its sleek, lightweight design, Fusion OA Plus provides gentle medial or lateral off- loading for unicompartmental osteoarthritis. The hinge utilizes a telescoping condyle with our exclusive, user friendly thumbwheel dial design that allows patients to easily adjust the level of off-loading without using a tool. The Fusion OA Plus hinge also incorporates an offset gauge with a large viewing window to clearly display the amount of load applied in half millimeter increments.

Improved Comfort and Fit with Airtech® Innovation

Another key feature of the Fusion OA Plus products is the AirTech frame pads that are specifically designed to improve comfort and fit. Airtech is a complete system of air mesh vents and grooved channel frame pads that increase airflow throughout the brace. The system allows cool air in and moves warm air and moisture away from the skin, improving comfort. The pad technology also improves suspension, reduces pinching and helps alleviate pressure points. Fusion OA Plus braces set the standard when it comes to suspension – it just stays where you put it!
