Clinical Trial 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.


Clinical Trial Description

The objectives of the study are to document that ROSA Knee System can provide intraoperative planning adjustment based on feedbacks obtained by laxity as well as gaps to locally preferred surgeon's operative philosophy. This will also provide accuracy, intraoperative soft tissue release as well as patient outcome on locally preferred surgical technique. The primary endpoint is defined as the mean absolute difference between X-Atlas image-based pre-op plan & intra-op final plan. The secondary endpoints include Kinematic Analysis, EuroQol 5 dimensions (EQ-5D), Rehabilitation record, Knee Society Score (KSS) 2011, image assessment and Safety up to 2 years postoperatively. ;
