Columbus REV F HC Gliding Surface - Posterior-stabilized total knee prosthesis

Intended purpose

The implant is used as a component part of a human knee endoprosthesis in combination with Columbus Revision components during revision of primary knee arthroplasty. Both osseous defects and soft tissue dysfunctions can be treated with Columbus Revision. Indicated for severe knee joint conditions that cannot be treated through other therapies: • Degenerative osteoarthritis • Rheumatoid arthritis • Posttraumatic arthritis • Symptomatic knee instability • Knee stiffness • Deformation of the knee joint • Used as revision implants in cases where primary implants have failed

Functional description

The Columbus REV F HC Gliding Surface is a fixed bearing, high constraint meniscal component made from UHMWPE and used in combination with all Columbus REV F Tibial components. The Gliding surface is delivered with a screw that corresponds to the insert height. The Gliding Surface has a post located centrally to interface with the cam on the femoral component. The mechanics of the interface restricts rotational motion and provides high varus/valgus stability.
