Abstract:

In recent years, unicompartmental knee arthroplasty (UKA) has achieved satisfactory results in the treatment of single-compartment knee osteoarthritis (KOA), with the rapid development of robot-assisted technology and gradually combined with clinical practice, robotic-assisted UKA (rUKA) has received extensive attention from clinicians because it improves the accuracy of osteotomy, prosthesis placement position, and reduces the error of lower limb force line after recovery. But rUKA also has its limitations, such as higher cost, longer surgery time and associated complications. At the same time, the early clinical effect is good, but the interim follow-up showed that rUKA did not have an advantage in prosthesis survival. Due to the lack of long-term follow-up results, it is unclear whether improving the precision of prosthesis implantation improves clinical outcomes and improves prosthesis survival. However, improving the precision of prosthetic implantation could be beneficial for patients, so robotic-assisted technology is worth using in the UKA. This article briefly introduced the history, composition and classification of rUKA, classification of surgical operating systems, current efficacy, prognosis, advantages and disadvantages, and reviewed the current clinical application of rUKA.
