Unloader One X

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 unicompartimental unloading of the knee joint.


• Moderate to severe unicompartmental knee osteoarthritis
• Degenerative meniscal tears
• Other unicompartmental knee conditions that may benefit from unloading such as:
– Articular cartilage defect repair
– Meniscal repair
– Avascular necrosis
– Condylar bone marrow lesions
– Tibial plateau fractures


• 3-Point Leverage System consisting of two Dynamic Force System (DFS) Straps, rigid shells and a single upright hinge contribute to a unicompartmental unloading of the knee joint.
• The unloading is effective only when needed, no condyle pressure during sitting or swing phase.
• A slender perforated frame with soft edges, contours easily to individual anatomies and remains discreet whether worn over or under clothing.
• Skin friendly liners and pads as well as a smooth inner surface of shells reduce probability of pressure points.
• The gastroc strap is positioned over thickest part of calf to help prevent migration.

• Tool-free SmartDosing® dials enable the patient to be in control of their pain level by fine-tuning the strap tension.
• Color-coded touchpoints and Quick-Fit buckles increase user-friendliness.
• Alignment guide on hinge facilitates correct positioning on the leg.
• Entire brace is machine washable (washbag included with product).
• Easily adaptable to individual needs and anatomical shapes.
• Field serviceable


• Measure calf circumference 15 cm (6″) below mid-patella. Leg in extension.
