Knee Surg Sports Traumatol Arthrosc. 2018 Dec;26(12):3636-3644. doi: 10.1007/s00167-018-4916-4. Epub 2018 Mar 24.
The purpose of the current prospective study was to assess the changes over time in patients tested at 6 months and 9 months after anterior cruciate ligament reconstruction (ACLR) with a return to sport (RTS) test battery. It was hypothesized that more patients passed RTS criteria at 9 months compared to 6 months.
Sixty-two ACLR patients performed a test battery at an average of 6.5 ± 0.7 and 9.5 ± 0.9 months after ACLR. All patients underwent a standardized rehabilitation protocol. The test battery consisted of the following tests: a jump-landing task assessed with the Landing Error Scoring System (LESS), three single-leg hop tasks (single-leg hop test, triple-leg hop test, side hop test), isokinetic quadriceps and hamstring strength at 60, 180 and 300°/s and two questionnaires (IKDC and ACL-RSI). Cut off criteria were set as Limb Symmetry Index (LSI) > 90% (for isokinetic strength and for single-leg hop tasks), LESS < 5, IKDC score within 15th percentage of healthy subjects and ACL-RSI > 56 respectively.
At 6 months, two patients (3.2%) passed all criteria. At 9 months, seven patients (11.3%) passed all criteria. Patients improved in all RTS criteria over time except for the IKDC score. Twenty-nine patients (46.8%) did not pass the strength criterion at 60°/s at 9 months after ACLR.
The percentages of patients passing all RTS criteria were low at both 6 and 9 months after ACLR. Quadriceps strength revealed persistent deficits and the lack of improvement in the IKDC score questionnaires shows insufficient self-reported knee function for RTS.

本前瞻性研究旨在评估前交叉韧带重建（ACL）后 6 个月和 9 个月接受重返运动（RTS）测试的患者的变化。假设与 6 个月相比，9 个月时有更多的患者通过 RTS 标准。
62 例 ACLR 患者在 ACLR 后平均 6.5±0.7 和 9.5±0.9 个月时进行了测试。所有患者均接受了标准化康复方案。测试包括以下测试：跳落地任务，使用落地错误评分系统（LESS）评估；三种单腿跳跃测试（单腿跳跃测试、三腿跳跃测试、侧跳测试）；60、180 和 300°/s 的等速股四头肌和腘绳肌力量以及两个问卷（IKDC 和 ACL-RSI）。截值标准设定为：等速力量和单腿跳跃任务的肢体对称性指数（LSI）>90%，LESS<5，IKDC 评分在健康受试者的第 15 个百分位内，ACL-RSI>56。
6 个月时，两名患者（3.2%）通过了所有标准。9 个月时，七名患者（11.3%）通过了所有标准。除 IKDC 评分外，所有 RTS 标准的患者在时间上均有所改善。29 名患者（46.8%）在 ACLR 后 9 个月时 60°/s 的等速力量标准未通过。
ACL 后 6 个月和 9 个月时，通过所有 RTS 标准的患者比例较低。股四头肌力量仍然存在缺陷，IKDC 评分问卷的改善不足表明膝关节功能自我报告不足以进行 RTS。
