Key features and benefits

The Atlas System is an implantable joint unloader for patients with medial knee osteoarthritis

Placed subcutaneously alongside the knee joint, the Atlas System incorporates advanced biomaterials designed to provide a clinically beneficial 13 kg (30 lbs.) of unloading. Importantly, the Atlas System absorbs excess joint load rather than transfer load to otherwise healthy areas of the joint.

Key benefits

Atlas materials

Streamlined surgical technique

The Atlas System features a streamlined surgical technique based on the patient’s own anatomy and allows the surgeon to visually confirm functional joint unloading during the procedure.
