Outcomes of robotic arm-assisted unicompartmental knee arthroplasty

Early outcomes of unicompartmental knee arthroplasty performed with a robotically assisted navigation system have been favorable. The surgical technique enhances accuracy of bone preparation and component positioning. Technical errors of the system have been minimal. The surgeon's learning curve is not adversely affected. Early patient outcomes are excellent and complications minimal. Further follow-up and study will help to determine whether these early outcomes are sustained over time.
