Unloader One® Custom

Unloader One® Custom


Unloader One® is a comfortable, lightweight, low-profile brace that provides excellent suspension and unloading leverage. This lightweight brace preserves the clinically-proven Össur® Unloader 3-Points of Leverage design by incorporating Dual Dynamic Force Straps that are easily fine-tuned via a Dynamic Force Control System. Color-coded Quick Fit Buckles simplify application and removal, while flexible shells and breathable liners, coated with Össur Sensil® Silicone, improve comfort and reduce migration, helping to ensure patient compliance. Recent research demonstrates that Unloader One reduces pain, improves function and decreases the use of pain medication.
