Robotic Total Knee Arthroplasty

Various robotic systems have been developed to improve the accuracy of implant selection, its positioning and alignment, and bone resection. These systems are currently used worldwide for total knee arthroplasty. Many studies have clearly demonstrated that robotic systems can accurately and reliably control variables such as lower leg alignment, joint-line maintenance, soft tissue balance, and component positioning. In addition, they are more accurate and reliable than those used for conventional total knee arthroplasty. To date, however, few studies have assessed the survivorship and functional outcomes of robot-assisted surgery, and we found no sufficiently powered studies that compared these two parameters between robot-assisted and conventional knee arthroplasty. Although larger survivorship studies are necessary for these comparisons, robotics will continue to progress toward becoming a valuable tool for decreasing the revision rate and improving functional outcomes.
