Unicompartmental knee arthroplasty (UKA) is frequently performed on active patients with symptomatic osteoarthritis who desire a quick return to sports. The aim of this study was to compare return to sport after lateral UKA performed by robotic-assisted and conventional techniques.
This retrospective study has assessed 28 lateral UKA (25 patients), 11 performed with robotic-assisted technique and 17 with conventional technique, between 2012 and 2016. The mean age was 65.5 and 59.5 years, with a mean follow-up of 34.4 months (range 15-50) and 39.3 months (range 22-68). Both groups were comparable pre-operatively. Sport habits and the details of the return to sports were assessed using University of California, Los Angeles Scale (UCLA) and direct questioning.
Robotic-assisted surgical technique provided significantly quicker return to sports than conventional technique (4.2 ±1.8 months; range 1-6 vs 10.5 ± 6.7 months; range 3-24; p < 0.01), with a comparable rate of return to sports (100% vs 94%). The practiced sports after lateral UKA were similar to those done preoperatively, with mainly low- and mid-impact sports (hiking, cycling, swimming, and skiing).
Robotic-assisted lateral UKA reduces the time to return to sports at pre-symptomatic levels when compared with conventional surgical technique. The return to sports rate after surgery is high in both groups. A long-term study would provide data on the prothesis wear in this active population.

单髁膝关节置换术（UKA）常用于有症状的骨关节炎活跃患者，他们希望能快速恢复运动。本研究的目的是比较机器人辅助技术和传统技术进行外侧UKA术后的运动恢复情况。
这项回顾性研究评估了2012年至2016年间的28例外侧UKA手术（25例患者），其中11例采用机器人辅助技术，17例采用传统技术。平均年龄分别为65.5岁和59.5岁，平均随访时间分别为34.4个月（范围15 - 50个月）和39.3个月（范围22 - 68个月）。两组术前情况具有可比性。使用加利福尼亚大学洛杉矶分校量表（UCLA）和直接询问的方式评估运动习惯和运动恢复细节。
机器人辅助手术技术比传统技术能显著更快地恢复运动（4.2±1.8个月；范围1 - 6个月 vs 10.5±6.7个月；范围3 - 24个月；p＜0.01），运动恢复率相当（100% vs 94%）。外侧UKA术后进行运动与术前相似，主要是低强度和中等强度运动（徒步、骑自行车、游泳和滑雪）。
与传统手术技术相比，机器人辅助外侧UKA能减少恢复到无症状水平运动的时间。两组术后运动恢复率都很高。长期研究将为这个活跃人群的假体磨损提供数据。
比较性回顾研究，III级。
