One hundred fifty-six patients with a total rupture of the anterior cruciate ligament (ACL) were reexamined 41 to 80 months after injury. They were randomized to three treatment groups: (1) repair and augmentation of the ACL with an iliotibial strip, (2) repair without augmentation, and (3) nonsurgical ACL treatment. Associated injuries of menisci and other ligaments were treated in the same way for the three groups. Two-thirds of the patients in the nonsurgically treated group complained of instability and 17% had had a subsequent reconstruction of the ACL at the follow-up examination. The group treated with an augmented repair had a less abnormal laxity measured by a laxity-testing device. Sixty-three percent returned to competitive sports, as compared with 27% in the nonsurgical group and 32% in the only repair group. Relative strength of the quadriceps and hamstrings muscles were similar for all groups. The augmented-repair group had better hop tests, reflecting a superior stability, whereas running was not affected by treatment but was correlated with the activity level.
156例前交叉韧带（ACL）完全断裂的患者在受伤后41至80个月接受了复查。他们被随机分为三个治疗组：（1）用髂胫束条修复并增强ACL，（2）不增强的修复，（3）非手术ACL治疗。三组患者半月板和其他韧带的相关损伤均采用相同的治疗方法。非手术治疗组中三分之二的患者抱怨关节不稳定，17%的患者在随访检查中随后进行了ACL重建。增强修复治疗组通过松弛测试装置测量的关节松弛异常程度较小。63%的患者恢复了竞技运动，相比之下，非手术组为27%，单纯修复组为32%。所有组的股四头肌和腘绳肌相对力量相似。增强修复组的单腿跳测试结果更好，反映出其稳定性更佳，而跑步不受治疗影响，但与活动水平相关。
