Objective: This study aims to compare 90-day postoperative complications, readmissions, and emergency department (ED) visits between robotic-assisted (RA-THA) and manual (M-THA) total hip arthroplasty.

Methods: A retrospective review of a multi-hospital database identified primary total hip arthroplasty patients between January 2016 and December 2021. The cohorts were 1-to-1 matched based on patient sex, age, and body mass index resulting in 8033 patients in each cohort (N = 16,066). Odds of 90-day revisits, readmission with >23 hours of observation, and ED visits were compared between cohorts. Complications reported during revisits and readmission were classified according to the Clinical Classification Software schema, using the International Classification of Diseases, 10th Revision codes, and compared using mixed-effect models.

Results: This study found an overall 90-day revisit rate of 8.3%. RA-THA was associated with significantly reduced odds of revisit within 90 days [odds ratio (OR): 0.71, 95% CI: 0.58-0.89, P = 0.002] and readmissions with >23 hours of observation (OR: 0.61, 95% CI: 0.48-0.77, P < 0.001). RA-THA patients had fewer readmissions with >23 hours of observation due to dislocations (RA-THA: 0.09%; M-THA: 0.39%, P < 0.001), surgical site infections (RA-THA: 0.04%; M-THA: 0.20%, P = 0.004), and wound infections/cellulitis (RA-THA: 0.01%; M-THA: 0.11%, P = 0.021). No difference in ED visits was observed between cohorts (OR: 0.92, 95% CI: 0.77-1.09, P = 0.3). RA-THA patients had more ED visits for dyspnea without pulmonary embolism (RA-THA: 0.20%; M-THA: 0.06%, P = 0.03).

Conclusion: RA-THA showed significantly lower odds of overall 90-day revisit rates and readmissions with >23 hours of observation, most notably for readmissions due to dislocation and surgical site infection/wound infections. There was no significant difference in the odds of ED visits between cohorts.

目标：本研究旨在比较机器人辅助（RA-THA）和手动（M-THA）全髋关节置换术后90天内的并发症、再入院和急诊科（ED）就诊情况。

方法：回顾性分析了2016年1月至2021年12月期间多医院数据库中的初次全髋关节置换患者。根据患者的性别、年龄和体质指数进行一对一匹配，每组各包含8033名患者（总计N = 16,066）。比较两组在90天内再次就诊、住院超过23小时以及急诊科就诊的概率。使用临床分类软件模式和国际疾病分类第十版代码对再入院期间报告的并发症进行分类，并使用混合效应模型进行比较。

结果：本研究发现总体90天内再次就诊率为8.3%。RA-THA与在90天内的复诊几率显著降低相关 [比值比（OR）：0.71，95% CI：0.58-0.89，P = 0.002] 和住院超过23小时的再入院率 (OR: 0.61, 95% CI: 0.48-0.77, P

结论：与手动全髋关节置换相比，机器人辅助全髋关节置换术后90天内的总体复诊率和住院超过23小时的再入院几率显著降低，特别是在因脱位和手术部位感染/伤口感染引起的再入院方面。两组间急诊科就诊的概率无显著差异。
