Abstract：
UNASSIGNED: Robotic-arm-assisted unicompartmental knee arthroplasty (UKA) is an excellent solution for patients suffering from single-compartment knee arthritis. While outcomes tend to be favorable for UKAs, revision operations, commonly due to component malpositioning and malalignment resulting in accelerated wear, are a major concern. Intraoperative technologies, such as robotic assistance, can help better ensure that implants are positioned based on a patient\'s specific anatomy and mechanical physiology. However, long-term survivorship and patient-reported satisfaction with robotic-assisted UKAs are limited. Therefore, the purpose of this study was to assess the 10-year outcomes of patients who underwent robotic-arm-assisted unicompartmental knee arthroplasty. Specifically, we evaluated: 1) 10-year survivorships; 2) patient satisfaction scores; and 3) re-operations.
UNASSIGNED: From a single surgeon and single institution, 185 patients who had a mean age of 65 years (range, 39 to 92) and a mean body mass index of 31.6 (range, 22.4 to 39) at a mean of 10 years follow-up were evaluated (range, 9 to 11). For all patients, the same robotic-assistive device was utilized intraoperatively, and all patients underwent standardized physical therapy and received standardized pain control management. Then 10-year survivorships with Kaplan-Meir curves, patient satisfaction evaluations with a 5-point Likert scale, and re-operations were assessed as primary outcomes.
UNASSIGNED: Overall implant survivorship was 99%, with only two patients requiring revision surgery. There was one patient who was converted to a total knee arthroplasty, while the other patient underwent polyethylene exchange at 5 weeks for an acute infection with successful implant retention. Overall, 97% of the patients were satisfied with their postoperative outcomes, with 81% of patients reporting being very satisfied. There were two other patients who required arthroscopic intervention: one to remove a cement loose body, the other to remove adhered scar from the fat pad and the anterior cruciate ligament.
UNASSIGNED: This study is one of the first to provide longer-term (mean 10-year) survivorship and patient-reported satisfaction outcomes for robotic-assisted UKA patients. These data show strong support for utilizing this surgical technique, as nearly all patients maintained their original prostheses and reported being satisfied after a mean of 10 years. Therefore, based on these results, we recommend the use of robotic assistance when performing UKAs.

摘要：
■机器人臂辅助单室膝关节置换术（UKA）是单室膝关节炎患者的绝佳解决方案。虽然结果往往对UKAs有利，修订操作，通常是由于部件错位和错位导致加速磨损，是一个主要问题。术中技术,比如机器人辅助，可以帮助更好地确保根据患者的特定解剖结构和机械生理学来定位植入物。然而,机器人辅助UKAs的长期生存率和患者报告满意度有限.因此,本研究的目的是评估接受机械臂辅助单室膝关节置换术的患者的10年结局.具体来说,我们评估了：1）10年生存率；2）患者满意度评分；和3）再次手术。
■来自单个外科医生和单个机构，185名平均年龄65岁的患者(范围，39至92），平均体重指数为31.6（范围，22.4至39)在平均10年的随访中进行了评估(范围，9至11）。对于所有患者来说，术中使用了相同的机器人辅助设备，所有患者均接受标准化物理治疗,并接受标准化疼痛控制管理.然后用Kaplan-Meir曲线计算10年生存率,使用5点Likert量表评估患者满意度，再次手术被评估为主要结果.
■植入物总生存率为99%，只有两名患者需要翻修手术。有一位病人转行全膝关节置换术,而另一名患者在5周时接受了聚乙烯交换，导致急性感染并成功保留植入物。总的来说,97%的患者对其术后结局满意,81%的患者报告非常满意。还有另外两名患者需要关节镜介入治疗：一名患者需要去除水泥松动的身体，另一种方法是去除脂肪垫和前十字韧带上粘附的疤痕。
这项研究是首次为机器人辅助的UKA患者提供长期（平均10年）生存率和患者报告的满意度结果之一。这些数据显示了对使用这种手术技术的强烈支持，因为几乎所有患者都维持了他们原来的假体，平均10年后报告满意。因此,基于这些结果，我们建议在执行UKAs时使用机器人辅助。
