We performed a prospective, randomized study on 76 patients (82 knees) scheduled for total knee arthroplasty to determine the effect of tourniquet release and hemostasis on the peri- and postoperative blood loss. Patients were randomly divided in two groups. Posterior cruciate retaining tricompartmental total knee prostheses were used in all. In group 1, the tourniquet was deflated intraoperatively after the prosthetic components were settled and hemostasis was done. In group 2, the tourniquet was released after the wound was closed and a compressive bandage was applied. Mean blood drainage was 880.85 ml (320-1,315) in group 1 and 745.36 ml (220-1,175) in group 2 ( p=0.03). The mean number of blood transfusions given, hemoglobin and hematocrit values, operation time, and tourniquet time were similar in both groups. Intraoperative tourniquet release and hemostasis does not reduce total blood loss in total knee arthroplasty.
我们对76例（82膝）计划行全膝关节置换术的患者进行了一项前瞻性随机研究，以确定止血带松开及止血对围手术期和术后失血的影响。患者被随机分为两组。均使用后交叉韧带保留型全髁膝关节假体。第1组在假体组件安置好并完成止血后，于术中松开止血带。第2组在伤口闭合并应用加压绷带后松开止血带。第1组平均引流量为880.85 ml（320 - 1315），第2组为745.36 ml（220 - 1175）（p = 0.03）。两组的平均输血次数、血红蛋白和血细胞比容值、手术时间及止血带使用时间相似。在全膝关节置换术中，术中松开止血带及止血并不能减少总失血量。
