A prospective study was designed to determine the impact of surgical timing on postoperative motion and stability following anterior cruciate ligament (ACL) reconstructive surgery. The study population was limited to acute ACL ruptures from downhill skiing undergoing arthroscopic ACL surgery without arthrotomy or surgical intervention for other ligamentous structures; 185 patients were entered into four separate groups based on the time interval from injury to surgery. Motion and stability were tested at multiple time points from the index surgery and adverse events were recorded. We found no statistical difference in restoration of extension or flexion in any group at any time point. KT-1000 data at 12 months showed a side-to-side difference of < or = 3 mm in 94%, with 6% showing a side-to-side difference of > 3 and < or = 5 mm. We conclude that, in this population, by using modern arthroscopic surgical techniques and an aggressive postoperative physical therapy protocol, motion and stability can be restored in a high percentage of patients and that surgical success is independent of the timing of surgery.
一项前瞻性研究旨在确定手术时机对前交叉韧带（ACL）重建术后活动度和稳定性的影响。研究对象仅限于因下坡滑雪导致急性ACL断裂且接受关节镜下ACL手术，未进行关节切开术或对其他韧带结构进行手术干预的患者；185例患者根据受伤至手术的时间间隔分为四个独立组。从初次手术起在多个时间点测试活动度和稳定性，并记录不良事件。我们发现，在任何时间点，任何组别的伸直或屈曲恢复情况均无统计学差异。12个月时的KT-1000数据显示，94%的患者两侧差值≤3 mm，6%的患者两侧差值＞3 mm且≤5 mm。我们得出结论，在该人群中，通过使用现代关节镜手术技术和积极的术后物理治疗方案，大部分患者的活动度和稳定性能够恢复，且手术成功率与手术时机无关。
