摘要

目的：年龄和性别会影响全膝关节置换术（TKA）的结果、并发症和翻修率。功能对齐（FA）是一种由机器人系统指导的个性化方法，已成为一种通过解决患者特定解剖和松弛来优化结果的策略。然而，关于年龄和性别对fa引导的机器人辅助TKA结果的影响的证据有限。方法：本回顾性研究评估了353例在FA原则指导下接受机器人辅助TKA的患者，随访时间至少为2年。患者根据年龄（≥75岁）分组。结果：术前临床和影像学评估显示各组间无统计学差异。与男性相比，女性有更多的外翻术前对齐。术后功能结果（KSS和FJS）和冠状排列在所有组之间具有可比性，唯一例外是女性组，尽管KSS评分相似，但FJS评分具有统计学意义（P = 0.02）。并发症和翻修率在两组间无统计学差异。结论：本研究表明，在FA指导下的机器人辅助TKA在不同性别和年龄组的预后、并发症发生率和翻修率方面具有可比性。这些发现表明，通过在不同的患者群体中提供一致的结果，FA可能有助于减少人口统计学差异。证据水平：III。

Robotic total knee arthroplasty with functional alignment yields comparable outcomes across age and gender groups

Objectives

Age and gender can influence total knee arthroplasty (TKA) outcomes, complications, and revision rates. Functional alignment (FA), a personalized approach guided by robotic systems, has emerged as a strategy to optimize outcomes by addressing patient-specific anatomy and laxities. However, limited evidence exists regarding the influence of age and gender on outcomes of FA-guided robotic-assisted TKA.

Methods

This retrospective study evaluated 353 patients who underwent robotic-assisted TKA guided by FA principles with a minimum of 2 years of follow-up. Patients were divided into groups based on age (≥75 years vs. <75 years) and gender (males vs. females). Outcomes assessed included functional scores [Knee Society Score (KSS) and Forgotten Joint Score (FJS)], complications, and revision rates. Coronal alignment was evaluated using preoperative and postoperative full-length weight-bearing X-rays and the data from the robotic system.

Results

Preoperative clinical and radiographic evaluations showed no statistically significant differences between age groups. Females had more valgus preoperative alignment compared to males. Postoperatively, functional outcomes (KSS and FJS) and coronal alignment were comparable across all groups, with the only exception being the female group, which reported statistically significant higher FJS scores (P = 0.02) despite similar KSS scores. Complication and revision rates did not differ in a statistically significant manner between groups.

Conclusions

This study demonstrated that robotic-assisted TKA guided by FA yields comparable outcomes, complication rates, and revision rates across gender and age groups. These findings suggest that FA may help reduce demographic disparities by providing consistent outcomes across diverse patient populations.
