Unicompartmental arthroplasty (UKA) is a highly effective treatment for isolated compartmental arthritis in the knee, especially among high volume surgeons. Implant loosening and technical problems related to bone resection and implant positioning may lead to higher rates of failure compared to total knee arthroplasty (TKA), particularly for low volume and novice surgeons. Robotic-assisted UKA was developed in an effort to improve implant positioning and kinematics, reduce technical error, and ultimately improve patient outcomes. Two semiautonomous robotic systems have demonstrated high levels of accuracy and precision compared to conventional techniques, quantify soft tissue balance, and preserve the bone by optimizing bony resections. Short-term clinical data is encouraging, but mid- and long-term data is needed to confirm that clinical benefits arise from the enhanced precision of robotic assistance. Cost-effectiveness and surgical efficiency continue to serve as barriers to more widespread adoption of robotic technology. Future study of mid- and long-term outcomes, as well as patient functional outcomes, will provide important insight into the cost-benefit analysis.
