We examined the assumption that patients undergoing same-day bilateral total knee arthroplasty (TKA) have a higher incidence of major peri-operative complications than patients who stage their procedures over the course of a year. Between April 2001 and March 2007, prospective data were collected using a total joint registry. Patients undergoing primary, bilateral, same-day, TKAs were compared to patients undergoing primary, staged, bilateral TKAs within 12 months of the index operation. A total of 2441 TKAs were performed on the same day, while 4231 were staged. There were no significant differences in 90-day mortality, thrombotic events and infections between the two groups. Performing same-day bilateral TKA does not predispose patients to increased cumulative incidence of major complications over staged arthroplasty.
我们检验了这样一个假设，即同期双侧全膝关节置换术（TKA）的患者比分期手术的患者在围手术期发生重大并发症的概率更高。2001 年 4 月至 2007 年 3 月期间，我们使用关节置换登记处收集了前瞻性数据。将同期行初次双侧 TKA 的患者与在指数手术后 12 个月内行初次分期双侧 TKA 的患者进行了比较。共有 2441 例 TKA 为同期手术，4231 例为分期手术。两组患者在 90 天死亡率、血栓事件和感染方面无显著差异。同期行双侧 TKA 并不会增加重大并发症的累积发生率，使患者处于不利地位。
