The purpose of this study was to determine if significant clinical differences exist in patient-reported outcome measures (PROMs) between PS and CR TKAs implanted using robotic-assisted technology. This was an IRB-approved retrospective study from an institutional database evaluating 214 knees in 190 patients. Inclusion criteria included: primary RA-TKA, age 22-89 at the time of surgery, preoperative coronal limb deformity within 15º of neutral alignment, and minimum 1-year follow-up. The PS cohort consisted of 103 patients with 107 RA-TKAs, whereas the CR cohort consisted of 87 patients with 107 RA-TKAs. Cohorts were compared on the basis of demographics and PROMs (KSS knee, KSS function, FJS-12, KOOS-JR, WOMAC, and 5-point satisfaction Likert scale) collected preoperatively and at 1-year follow-up. Statistical analyses comparing measures were conducted via Student's t tests for continuous data and Chi-squared analyses for categorical data. There were no significant differences identified in short-term PROMs at 1-year follow-up between cohorts (all p values > 0.05). 93.1% of patients with CR knees and 94.7% of patients with PS knees reported a satisfaction level of "very satisfied" or "satisfied". Revision arthroplasty occurred in six knees (2.8%, 3 knees in CR cohort, 3 knees in PS cohort) with no differences in overall complications between groups. The use of RA-TKA technology promoted high patient satisfaction scores within this study, independent of CR or PS implant type with no significant differences in PROMs, satisfaction, revisions, or complications between the two groups.
本研究旨在确定使用机器人辅助技术植入的 PS 和 CR TKA 之间，在患者报告的结局测量（PROM）方面是否存在显著的临床差异。这是一项经过机构审查委员会批准的回顾性研究，来自一个评估了 190 名患者的 214 个膝关节的数据库。纳入标准包括：原发性 RA-TKA、手术时年龄在 22-89 岁之间、术前冠状位肢体畸形在中立对线 15°以内、以及至少 1 年的随访。PS 队列包括 103 名患者的 107 个 RA-TKA，而 CR 队列包括 87 名患者的 107 个 RA-TKA。两组患者在人口统计学数据和 PROM（KSS 膝关节评分、KSS 功能评分、FJS-12、KOOS-JR、WOMAC 和 5 分满意度 Likert 量表）方面进行比较，这些数据在术前和 1 年随访时收集。比较各项措施的统计分析通过连续数据的学生 t 检验和分类数据的卡方分析进行。在 1 年随访时，两组患者的短期 PROM 无显著差异（所有 p 值均>0.05）。CR 膝关节患者中 93.1%和 PS 膝关节患者中 94.7%报告了“非常满意”或“满意”的满意度水平。有六例膝关节（2.8%，CR 队列中有 3 例，PS 队列中有 3 例）需要翻修，两组之间总体并发症无差异。在本研究中，使用 RA-TKA 技术可提高患者的满意度评分，与 CR 或 PS 植入物类型无关，两组患者的 PROM、满意度、翻修和并发症无显著差异。
