ROSA Knee Intraoperative Planning Flexibility Study

Summary

The purpose of this study is to verify that an orthopedic surgical assist robot (ROSA Knee System) can provide intraoperative adjustment of osteotomy angle and volume for total knee arthroplasty (TKA) based on feedbacks obtained from intraoperative soft tissue conditions. A total 80 cases will be enrolled at one study site with a postoperative follow-up period of 2 years.
