Optimizing Total Knee Arthroplasty With ROSA® Robotic Technology

A new robotic platform (ROSA® Knee system, Zimmer Biomet, Warsaw, Indiana) for total knee arthroplasty (TKA) has been created to increase precision of bony resections and knee balancing while maintaining surgeon autonomy. Our aim is to discuss: (1) the background of robotic technology in orthopedics, (2) current literature and potential benefits of the ROSA® Knee system, and the (3) optimal surgical technique for this specific robotic TKA platform. Early literature regarding this robotic system is promising as studies have shown precision of its bony resections, accuracy of overall limb alignment, and low early revision rates. There is a need for continued research on clinical outcomes using this platform, and the intention is to provide a review with insight into the potential advantages of robotics and the ideal surgical technique for successful use of this system.
