Muscle deficits in 58 patients with chronic anterior cruciate ligament (ACL) insufficiency were evaluated after completion of a 6 month rehabilitation program. Quadriceps and hamstring torques were measured on a modified Cybex II isokinetic dynamometer. Twenty-nine of our patients were tested just prior to undergoing ACL reconstruction, and patients who were continuing to tolerate their conditions served as controls. For the surgical group, significant quadriceps deficits (P less than 0.01) were found for all speeds and at both the 30 and 60 degrees positions. The nonsurgical group had significant deficits at the 30 degrees position at 180 degrees/sec, and at 60 degrees for the 0 degree/sec and 30 degrees/sec. However, in comparing the two groups no significant differences were noted. Regarding hamstring deficits in the surgical group, significant deficits were seen only at 30 degrees of flexion at 180 degrees/sec. The nonsurgical group had similar deficits. Of interest was the observation that the hamstring:quadriceps (H:Q) ratio was found to be both speed-position dependent. Overall, no correlation was found between the presence of strength deficits following a rehabilitation program and the need for surgery.
在一项为期6个月的康复计划完成后，对58例慢性前交叉韧带（ACL）功能不全患者的肌肉功能缺陷进行了评估。使用改良的Cybex II等速测力计测量股四头肌和腘绳肌的扭矩。29例患者在接受ACL重建手术前接受测试，继续耐受自身病情的患者作为对照组。对于手术组，在所有速度以及30度和60度位置均发现显著的股四头肌功能缺陷（P小于0.01）。非手术组在180度/秒的速度下30度位置以及0度/秒和30度/秒速度下60度位置存在显著缺陷。然而，比较两组时未发现显著差异。关于手术组的腘绳肌功能缺陷，仅在180度/秒的30度屈曲时发现显著缺陷。非手术组有类似的缺陷。有趣的是，观察发现腘绳肌与股四头肌（H:Q）的比率与速度和位置有关。总体而言，康复计划后力量缺陷的存在与手术需求之间未发现相关性。
