Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study has been designed to document the long-term outcome of the E1® Tibial Bearings used with the Vanguard® Knee System in 500 patients receiving total knee arthroplasty. All patients will receive the E1® Tibial Bearing in a Vanguard® knee replacement. Radiographic analysis and patient reported outcomes will be used as follow-up measures to track wear, mechanical performance, and patient satisfaction.
