Ossur Unloader One Arthritis Knee Brace


The Ossur Unloader One Knee Brace is a lightweight, easy to use, non-surgical treatment option for the symptoms associated with osteoarthritis (OA) of the knee. Numerous clinical studies have proven the Unloader One OTS® to reduce one's reliance on pain medications, enhance mobility, and improve overall knee function during walking activities. Its lightweight design is easy to use and apply for use underneath clothes.

The Unloader One improves your quality of life with a comfortable brace that exemplifies advanced technology and an understanding of biomechanics and design. It's half the weight of the original design that debuted years ago, and effectively restores mobility while reducing pain.  As with the custom model, this osteoarthritis unloader knee brace preserves the clinically-proven Ossur Unloader 3-Points of Leverage design by incorporating Dual Dynamic Force Straps that are easily fine tuned via a Dynamic Force Control System. The rachet-style buckles allow for easy fitting and fine tune adjustments for enhancing support. Color-coded straps and breathable padding with Össur Sensil® Silicone are specially designed to improve suspension and ensure a secure fit. The Unloader One knee brace provides greater comfort and patient compliance.

New: SmartDosing, powered by Boa®Technology, provides patients with a simplified, single-hand dosing dial for on-the-fly adjustability of the dual Dynamic Force Straps (DFS), helping them better manage their unicompartmental OA knee pain. And, by utilizing the new SmartDosing dial, users can easily adjust the dual DFS tension right through their clothes.
