ATTUNE Revision CRS Rotating Platform Insert - Prosthesis, knee, internal, insert component

Intended purpose

The ATTUNE Revision Constrained Revision System (CRS) Rotating Platform Insert 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 CRS Rotating Platform Insert is made from UHMWPE. It has a symmetric design with a spine and has a titanium reinforcing pin. Restores the tibiofemoral articulating surface and provides smooth surface to replace the tibial plateau and articulate with the condylar surface of the femoral component. Also provides a wider, reinforced post for additional varus-valgus stability to offset collateral ligament laxity. The insert is seated to the tibial base by top down impaction.
