Unity Knee™ (PS)
-Total Knee

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™ PS (posterior stabilized) femoral component and PS tibial insert variant is indicated for use where the posterior cruciate ligament is non-functioning or absent, resulting in joint instability.
