We prospectively followed 171 patients who underwent bilateral unicompartmental knee replacement (UKR) over a period of two years. Of these, 124 (72.5%) underwent a simultaneous bilateral procedure and 47 (27.5%) underwent a staged procedure. The mean cumulative operating time and length of hospital stay were both shorter in the simultaneous group, by 22.5 minutes (p < 0.001) and three days (p < 0.001), respectively. The mean reduction in haemoglobin level post-operatively was greater by 0.15 g/dl in the simultaneous group (p = 0.023), but this did not translate into a significant increase in the number of patients requiring blood transfusion (p = 1.000). The mean hospital cost was lower by $8892 in the simultaneous group (p < 0.001). There was no significant difference in the rate of complications between the groups, and at two-year follow-up there was no difference in the outcomes between the two groups. We conclude that simultaneous bilateral UKR can be recommended as an appropriate treatment for patients with bilateral medial compartment osteoarthritis of the knee.
我们前瞻性地随访了 171 例在两年内接受双侧单髁膝关节置换术（UKR）的患者。其中，124 例（72.5%）接受了同期双侧手术，47 例（27.5%）接受了分期手术。同期组的累计手术时间和住院时间均缩短了 22.5 分钟（p < 0.001）和 3 天（p < 0.001）。同期组术后血红蛋白水平下降幅度更大，为 0.15 g/dl（p = 0.023），但这并未导致需要输血的患者数量显著增加（p = 1.000）。同期组的平均住院费用降低了 8892 美元（p < 0.001）。两组之间的并发症发生率没有显著差异，在两年的随访中，两组的结果也没有差异。我们得出结论，同期双侧 UKR 可作为治疗双侧膝关节内侧间室骨关节炎患者的一种合适的治疗方法。
