To compare the rates of perioperative complications in matched patients undergoing simultaneous bilateral total knee arthroplasty, or staged bilateral total knee arthroplasty.
A total of 219 cases of bilateral total knee arthroplasty were performed from October 1996 to October 2006. It consisted 171 simultaneous and 48 staged (group B) bilateral total knee arthroplasty. Forty-eight patients were matched with group B for age and sex from simultaneous group (group A). A retrospective review of each group was conducted to compare the rates of perioperative complications.
No significant differences between the two matched groups were found with regard to preoperative co-morbidities (P > 0.05). The percentage of patients who had cardiovascular and cerebrovascular complications was significantly higher in the simultaneous group than in the staged group (P < 0.05).
Preoperative health status must be assessed carefully. Patients must be fully informed of the risks of simultaneous bilateral total knee arthroplasty before surgery. Active prevention of perioperative complications must be applied after surgery.
比较同期双侧全膝关节置换术和分期双侧全膝关节置换术患者围手术期并发症的发生率。
1996年10月至2006年10月共进行了219例双侧全膝关节置换术。其中包括171例同期双侧全膝关节置换术和48例分期双侧全膝关节置换术（B组）。从同期组（A组）中选取48例年龄和性别与B组匹配的患者。对每组进行回顾性分析以比较围手术期并发症的发生率。
两组匹配患者术前合并症无显著差异（P>0.05）。同期组发生心血管和脑血管并发症的患者百分比显著高于分期组（P<0.05）。
术前必须仔细评估健康状况。术前必须让患者充分了解同期双侧全膝关节置换术的风险。术后必须积极预防围手术期并发症。
