The clinical results of bilateral total knee replacement staged at a one-week interval during a single hospital admission were compared with bilateral total knee replacements performed under the same anaesthetic and with bilateral total knee replacements performed during two separate admissions. The data were retrospectively reviewed. All operations had been performed by the same surgeon using the same design of prosthesis at a single institution. The operative time and length of stay for the one-week staged group were comparable with those of the separate admission group but longer than for the patients treated under one anaesthetic. There was a low rate of complications and good clinical outcome in all groups at a mean follow-up of four years (1 to 7.2). The group staged at a one-week interval had the least blood loss (p = 0.004). With appropriate patient selection, bilateral total knee replacement performed under a single anaesthetic, or staged at a one-week interval, is a safe and effective method to treat bilateral arthritis of the knee.
将单次住院期间间隔一周分期进行的双侧全膝关节置换的临床结果，与在相同麻醉下进行的双侧全膝关节置换以及在两次单独住院期间进行的双侧全膝关节置换进行比较。对数据进行回顾性分析。所有手术均由同一位外科医生在单一机构使用相同设计的假体完成。一周分期组的手术时间和住院时间与单独住院组相当，但比在一次麻醉下治疗的患者更长。在平均四年（1至7.2年）的随访中，所有组的并发症发生率都很低，临床结果良好。间隔一周分期的组失血量最少（p = 0.004）。通过适当选择患者，在单次麻醉下或间隔一周分期进行双侧全膝关节置换是治疗双侧膝关节关节炎的一种安全有效的方法。
