The Unity Knee is a fixed bearing total knee replacement that is designed to preserve the medial joint line and provide ligament isometry throughout the range of motion. The system consists of a cobalt chromium alloy (CoCr) single radius femoral design component, a UHMWPE polyethylene tibial insert, a cobalt chromium alloy (CoCr) tibial tray with a titanium alloy keel extension and all-polyethylene patellar component for use in primary and revision total knee arthroplasty. The Unity Knee™ CR (cruciate retaining) femoral component is intended for use in conjunction with the CR tibial insert where the posterior cruciate ligament (PCL) is functional.
