Less than 50% of athletes pass criteria to return to sports (RTS) 6 months after ACL reconstruction (ACLR). Using data on 38 noncopers, we hypothesized that preoperative age, quadriceps strength index (QI), and knee flexion moments (KFM) during gait would predict the ability to pass/fail RTS criteria and that preoperative quadriceps strength gains would be predictive of passing RTS criteria. Gait analysis and strength data were collected before and after a preoperative intervention and 6 months after ACLR. Age, QI, and KFM each contributed to the predictability to pass or fail RTS criteria 6 months after ACLR. Collectively, the variables predict 69% who would pass and 82% who would fail RTS criteria 6 months after ACLR. Younger athletes who have symmetrical quadriceps strength and greater KFM were more likely to pass RTS criteria. Further, 63% of those who increased preoperative quadriceps strength passed RTS criteria, whereas 73% who did not failed. Increasing quadriceps strength in noncopers before ACLR seems warranted.
在进行前交叉韧带重建术（ACLR）6个月后，不到50%的运动员达到恢复运动（RTS）的标准。利用38名非顺应者的数据，我们假设术前年龄、股四头肌力量指数（QI）和步态期间的膝关节屈曲力矩（KFM）将预测通过/未通过RTS标准的能力，并且术前股四头肌力量的增加将预测通过RTS标准。在术前干预前后以及ACLR后6个月收集步态分析和力量数据。年龄、QI和KFM各自对ACLR后6个月通过或未通过RTS标准的可预测性有贡献。总体而言，这些变量可预测ACLR后6个月69%能通过RTS标准的人和82%不能通过RTS标准的人。股四头肌力量对称且KFM更大的年轻运动员更有可能通过RTS标准。此外，术前股四头肌力量增加的人中有63%通过了RTS标准，而未增加的人中有73%未通过。在ACLR前增加非顺应者的股四头肌力量似乎是有必要的。
