In this retrospective study, we compared forty-five patients who had undergone same-day bilateral total knee arthroplasties with 144 patients who had undergone unilateral total knee arthroplasty procedures. All procedures were performed by a single surgeon using a single prosthetic design between June 1994 to May 1996. The issues studied were the length of hospital stay, hospital charges, units of blood transfused, units of homologous blood transfused, and the rate and type of complications. This study also examined the usage and financial charges of extended care facilities and/or home health care following discharge from the hospital. Results show that, for patients suffering from symptomatic bilateral knee disease, the same-day bilateral total knee procedure is significantly less costly than staged bilateral procedures. The rate and type of complications seen in the same-day bilateral cases were not significantly different from complications seen in unilateral cases.
在这项回顾性研究中，我们将45例接受同日双侧全膝关节置换术的患者与144例接受单侧全膝关节置换术的患者进行了比较。所有手术均由同一位外科医生在1994年6月至1996年5月期间使用单一假体设计完成。研究的问题包括住院时间、住院费用、输血单位、同源输血单位以及并发症的发生率和类型。本研究还考察了出院后延伸护理设施和/或家庭医疗护理的使用情况及费用。结果显示，对于患有双侧膝关节症状性疾病的患者，同日双侧全膝关节手术的费用明显低于分期双侧手术。同日双侧病例中出现的并发症发生率和类型与单侧病例中所见的并发症无显著差异。
