To evaluate the effect of tourniquet use during anterior cruciate ligament reconstruction, 40 consecutive patients were randomized into two groups: Group I (tourniquet) and Group II (no tourniquet). Preoperative evaluation included electromyography, measurement of thigh and calf girth, and determination of serum creatinine phosphokinase levels. Initial postoperative evaluations included serial creatinine phosphokinase determinations. At 1 and 6 months postoperatively, the electromyographic examination was repeated and thigh and calf girth measurements were obtained. At 6 months and 1 year after surgery, the following evaluations were made: thigh and calf girth, KT-1000 arthrometric testing, isokinetic testing of quadriceps and hamstring muscles, single-legged hop test for time, single-legged hop test for distance, and the Lysholm knee score. In Group I, the tourniquet was inflated for an average of 87 minutes, with an average pressure of 269 mm Hg. At 1 month postoperatively, 6 of 20 patients in Group I had positive electromyographic recordings (compared with 2 of 20 in Group II, P = 0.08). At 1 month, thigh girths measured 10 cm proximal to the medial joint line suggested more atrophy in the tourniquet group (P = 0.07). At 6 months, all electromyographic recordings had returned to normal. At 6 months and 1 year postoperatively, girth measurements, isokinetic strength testing, functional testing, KT-1000 arthrometer evaluation, and the Lysholm knee scores were similar for both groups.
为评估在前交叉韧带重建术中使用止血带的效果，40例连续患者被随机分为两组：第一组（使用止血带）和第二组（不使用止血带）。术前评估包括肌电图检查、大腿和小腿围度测量以及血清肌酸磷酸激酶水平测定。术后初期评估包括连续测定肌酸磷酸激酶。术后1个月和6个月时，重复肌电图检查并测量大腿和小腿围度。术后6个月和1年时，进行以下评估：大腿和小腿围度、KT-1000关节测量试验、股四头肌和腘绳肌等速肌力测试、单腿跳定时试验、单腿跳远试验以及Lysholm膝关节评分。在第一组中，止血带平均充气87分钟，平均压力为269毫米汞柱。术后1个月时，第一组20例患者中有6例肌电图记录呈阳性（而第二组20例中有2例，P = 0.08）。在1个月时，在内侧关节线近端10厘米处测量的大腿围度显示止血带组萎缩更明显（P = 0.07）。6个月时，所有肌电图记录均恢复正常。术后6个月和1年时，两组的围度测量、等速肌力测试、功能测试、KT-1000关节测量仪评估以及Lysholm膝关节评分相似。
