Clinical Trial Summary

The purpose of the study is to determine the survivorship of robotic-arm assisted MCK medial onlay Unicompartmental knee arthroplasty implants at two, five and tem year follow up.

Description:

The purpose of the study is to determine the survivorship of robotic-arm assisted MCK medial onlay unicompartmental knee arthroplasty implants at two, five, and ten year follow up. Study participants will also be asked about their level of satisfaction with their knee function following their robotic-arm assisted Unicompartmental Arthroplasty.
