INTRODUCTION The objective was to evaluate if the use of CA-THA was associated with lower complications in the first 90 days following THA compared with conventional THA. METHODS The Nationwide Readmission Database (NRD) was queried to identify patients who underwent THA between 2012 and 2014. The primary outcome was arthroplasty-related complications within the first 90 days following THA. Multivariate models predicting the risk of complications, readmission, and revision-related readmission within 90 days of discharge were created. RESULTS A total of 309,252 patients with a minimum 90-day follow-up following elective primary THA were identified. After controlling for age, sex, comorbidities, indication, income, and type of insurance, the use of CA during THA resulted in a 12% reduced odds of 90-day complications (OR 0.88, 95% CI 0.77-0.99, p = 0.04). DISCUSSION The use of CA-THA resulted in lower 90-day complication rates and readmission rates compared with traditional THA after controlling for confounding variables. There was no significant difference in the rates of revision surgery between the groups within the first 90 days.

全髋关节置换术的计算机导航与较低的并发症和 90 天再入院相关：一项全国范围内的关联分析。


引言 目的是评估与传统 THA 相比，使用 CA-THA 是否可以降低 THA 术后前 90 天内的并发症。方法 查询全国再入院数据库 (NRD)，以确定 2012 年至 2014 年间接受过 THA 的患者。主要结局是 THA 后前 90 天内与关节置换术相关的并发症。创建了预测出院 90 天内并发症、再入院和翻修相关再入院风险的多变量模型。结果 共有 309,252 名患者在择期初次 THA 后接受了至少 90 天的随访。在控制年龄、性别、合并症、适应症、收入和保险类型后，THA 期间使用 CA 可使 90 天并发症的几率降低 12%（OR 0.88，95% CI 0.77-0.99，p = 0.04） ）。讨论 在控制混杂变量后，与传统 THA 相比，使用 CA-THA 可以降低 90 天并发症率和再入院率。前 90 天内各组之间的翻修手术率没有显着差异。
