ATTUNE Revision Tibial Base Rotating Platform - Uncoated knee tibia prosthesis, metallic

Intended purpose

The ATTUNE Revision Tibial Base Rotating Platform is a component of the ATTUNE Revision Knee System which is used in Total Knee Arthroplasty (TKA). The ATTUNE Revision Knee System is intended to provide a functional articulating knee joint in skeletally mature patients with a severe painful knee and impaired knee function and/or after a failed previous implant. It is indicated for: 1. A severely painful and/or disabled joint (typically due to non-inflammatory degenerative joint disease) 2. Failed previous knee surgery, typically unsuccessful knee replacement, osteotomy or other knee procedures 3. TKA patients with ligamentous insufficiency and/or bone loss which, in the clinical judgement of the surgeon, requires increased bearing constraint and/or supplemental fixation

Functional description

The ATTUNE Revision Tibial Base Rotating Platform is manufactured from Co-Cr-Mo alloy and includes a removable poly plug. The surface is textured for cemented fixation. It utilizes a central hole to incorporate the post of the ATTUNE Revision RP insert. The tibial base provides a stable platform for the tibial insert that distributes compressive loads across the proximal tibia and a keel for fixation within the metaphyseal region of the tibia. It is stemmable and augmentable.
