The effects of using a tourniquet during total knee arthroplasty were studied in 80 patients randomly allocated to two groups, either with or without a tourniquet. The groups were similar in mean age, gender, preoperative knee score and radiographic grading and the patients were all operated on by the same surgeon using one type of prosthesis. There was no significant difference between the two groups in operating time or total blood loss but postoperative pain was less in the patients in whom a tourniquet had not been used. They achieved straight-leg raising and knee flexion earlier and had fewer superficial wound infections and deep-vein thromboses. Total knee arthroplasty can be safely performed without the use of the tourniquet with the benefit that several adverse effects associated with its use can be avoided.
在80例患者中研究了全膝关节置换术中使用止血带的效果，这些患者被随机分为两组，一组使用止血带，另一组不使用止血带。两组患者在平均年龄、性别、术前膝关节评分和影像学分级方面相似，并且所有患者均由同一位外科医生使用同一种假体进行手术。两组在手术时间或总失血量方面无显著差异，但未使用止血带的患者术后疼痛较轻。他们更早实现直腿抬高和膝关节屈曲，并且浅表伤口感染和深静脉血栓形成较少。全膝关节置换术可以在不使用止血带的情况下安全进行，这样可以避免与其使用相关的几种不良反应。
