The Unloader One X offloading knee brace's patented 3-Point Leverage System “unloads” the pressure from your affected knee compartment, resulting in a reduction of knee osteoarthritis pain.

Unloader knee braces for osteoarthritis unload the affected, painful side of the knee using a 3-Point Leverage System.  The thigh and calf shells account for two points of leverage, while the Dynamic Force System™ (DFS) straps provide the third. This system “unloads” the pressure from the affected area, providing a clinically proven reduction in OA knee pain.

Unloader One X knee brace for osteoarthritis features a lightweight, low-profile design, which is barely noticeable and fits discreetly under clothing.  SmartDosing® dials provide you with simple, single-hand control for on-the-fly adjustability, helping you better manage knee osteoarthritis pain.

Unloader One X improves mobility by providing pain relief from knee osteoarthritis and degenerative meniscal tears.

It features Össur's unique patented and clinically proven 3-point Leverage System that generates unicompartmental unloading of the knee joint.
