»: Bilateral total knee arthroplasty (BTKA) is an effective surgical treatment for bilateral knee arthritis and can be performed as a simultaneous surgery under a single anesthetic setting or as staged surgeries on separate days.
»: Appropriate patient selection is important for simultaneous BTKA with several factors coming into consideration such as age, comorbidities, work status, and home support, among others.
»: While simultaneous BTKA is safe when performed on appropriately selected patients, current evidence suggests that the risk of complications after simultaneous BTKA remains higher than for staged BTKA.
»: When staged surgery is preferred, current evidence indicates that complication risks are minimized if the 2 knees are staged at least 3 months apart.
»: Simultaneous BTKA is the economically advantageous treatment option relative to staged BTKA, primarily because of shorter total operative time and total hospital stay.
»: 双侧全膝关节置换术（BTKA）是治疗双侧膝关节关节炎的有效手术方法，可以在单次麻醉下同时进行，也可以分两天进行分期手术。
»: 对于同时进行双侧全膝关节置换术，适当的患者选择非常重要，需要考虑多个因素，如年龄、合并症、工作状态和家庭支持等。
»: 虽然在适当选择的患者中同时进行 BTKA 是安全的，但现有证据表明，同时进行 BTKA 的并发症风险仍然高于分期 BTKA。
»: 当分期手术更受欢迎时，如果将两个膝关节至少间隔 3 个月分期，则当前证据表明并发症风险最小化。
»: 与分期 BTKA 相比，同时进行 BTKA 是具有经济优势的治疗选择，主要是因为总手术时间和总住院时间更短。
