As a treatment modality for advanced knee osteoarthritis, total knee arthroplasty is well established and has been performed on many patients over time. To improve surgical outcomes, fixed-bearing implant insertion with robotic-assisted TKA has been introduced; however, the insertion of mobile-bearing (MB) implants with the same method is challenging. The aim of this study was to compare the short-term postoperative follow-up outcomes of MB implant insertion using a robotic-assisted TKA system and conventional TKA. We investigated functional improvement in the knees of 60 patients who underwent the insertion of MB implants using either robotic-assisted TKA or conventional TKA. Isokinetic muscular function, range of motion, the Western Ontario and McMaster Universities Osteoarthritis Index score, visual analog scale (VAS) score, and Knee Society Score (KSS) were measured 6 months after surgery. The statistical analysis of outcome measurements was performed using the Mann-Whitney U test and the Wilcoxon signed-rank test. Some isokinetic muscular functions, as well as Knee Society Scores (pain and function) and VAS scores, were significantly higher in patients who underwent MB insertion with robotic-assisted TKA than in those who underwent conventional TKA. When an MB implant is inserted using a robotic-assisted TKA system, a better surgical outcome can be expected.
作为治疗晚期膝关节骨关节炎的一种方法，全膝关节置换术已经得到广泛应用，并且已经有许多患者接受了这种手术。为了提高手术效果，已经引入了机器人辅助 TKA 下的固定轴承植入物插入术；然而，使用相同的方法插入活动轴承（MB）植入物具有挑战性。本研究的目的是比较使用机器人辅助 TKA 系统和传统 TKA 插入 MB 植入物的短期术后随访结果。我们研究了 60 名接受 MB 植入物插入的患者的膝关节功能改善情况，这些患者分别接受了机器人辅助 TKA 或传统 TKA 治疗。术后 6 个月，我们测量了等速肌肉功能、关节活动度、西安大略和麦克马斯特大学骨关节炎指数评分、视觉模拟评分（VAS）和膝关节学会评分（KSS）。使用曼-惠特尼 U 检验和 Wilcoxon 符号秩检验对结果测量的统计分析进行了分析。在接受机器人辅助 TKA 下 MB 插入的患者中，一些等速肌肉功能以及膝关节学会评分（疼痛和功能）和 VAS 评分明显高于接受传统 TKA 治疗的患者。当使用机器人辅助 TKA 系统插入 MB 植入物时，可以预期更好的手术效果。
