To investigate the differences in demographic, anthropometric, biomechanical, and/or performance variables between those that do (responders) and do not (non-responders) exhibit reductions in knee abduction moments after an anterior cruciate ligament injury prevention program (ACL-IPP).
Forty-three adolescent female athletes completed biomechanical (3D motion analysis of a drop vertical jump) and performance testing before and after randomization into a 6-week ACL-IPP. Participants were classified into responders and non-responders based on their level of reduction of knee abduction moment from pre- to post-test.
Compared to non-responders, responders exhibited increased hip adduction excursion at baseline (p = 0.02) and trended towards attending more training sessions (p = 0.07) and participating in soccer and not basketball (p = 0.07). Responders also showed greater improvements in hip flexion angles (p = 0.02) and moments (p < 0.001), and knee abduction angles (p < 0.001) and excursions (p = 0.001). There were no significant differences in age or experience with prior injury prevention programs (n.s.).
After an ACL-IPP, athletes that exhibit the greatest reduction in knee abduction moments exhibit greater hip adduction excursion at baseline and show corresponding improvements in hip flexion and knee abduction kinematics and hip flexion moments. These results can help clinicians prospectively identify individuals that may not respond to an ACL-IPP and target individualized training for those at risk of injury.

研究在接受前交叉韧带损伤预防计划（ACL-IPP）后，膝关节外展力矩降低的患者（响应者）与未降低的患者（非响应者）之间在人口统计学、人体测量学、生物力学和/或表现变量方面的差异。
43 名青春期女性运动员在随机分配到 6 周 ACL-IPP 前后完成了生物力学（3D 运动分析下的垂直跳）和表现测试。根据膝关节外展力矩从术前到术后的降低程度，将参与者分为响应者和非响应者。
与非响应者相比，响应者在基线时髋关节内收幅度更大（p = 0.02），并且倾向于参加更多的训练课程（p = 0.07），并且参加足球而不是篮球（p = 0.07）。响应者的髋关节屈曲角度（p = 0.02）和力矩（p < 0.001）以及膝关节外展角度（p < 0.001）和幅度（p = 0.001）也有更大的改善。年龄或以前受伤预防计划的经验（无统计学差异）没有显著差异。
在 ACL-IPP 后，膝关节外展力矩降低最大的运动员在基线时髋关节内收幅度更大，并且髋关节屈曲和膝关节外展运动学以及髋关节屈曲力矩也相应改善。这些结果可以帮助临床医生前瞻性地识别可能对 ACL-IPP 无反应的个体，并针对那些有受伤风险的个体进行个体化训练。
