Active management of modifiable factors during the early rehabilitation stage can help patients who have undergone anterior cruciate ligament (ACL) reconstruction successfully return to sports. This study aimed to determine predictors for performance on the single-leg hop test and Tegner activity score 12-month post-ACL reconstruction, based on knee function assessed 3-month postsurgery.
Prospective cohort study.
Ninety-one patients who underwent ACL reconstruction were recruited. Multivariate logistic regression analysis was performed to identify predictors of the one hop test and Tegner activity score 12-month postsurgery, based on a knee examination performed 3 months after ACL reconstruction. Factors evaluated at 3 months included the Biodex balance system anteroposterior and mediolateral indexes; Y balance test anterior, posteromedial, and posterolateral reaches; knee extensors and flexors peak torque per body weight; and knee extensors and flexors average power per body weight.
The knee extensor peak torque per body weight (PT/BW) and Biodex balance system-mediolateral index with cutoff values of 132 N·m/kg and 0.45, respectively were identified as predictors for achieving a limb symmetric index within 10% on the hop test. Furthermore, achieving a Tegner activity score over 6 was predicted by Y balance test-posteromedial reach and knee flexors average power per body weight, with cutoff values of 92.5 cm and 122 W/kg, respectively.
Three months following ACL reconstruction, knee extensor peak torque, and mediolateral balance predicted performance on the hop test, while dynamic posteromedial balance and knee flexors average power predicted rotational ability, at the 12-month assessment.
在早期康复阶段积极管理可改变因素有助于前交叉韧带（ACL）重建术后的患者成功恢复运动。本研究旨在根据术后3个月评估的膝关节功能，确定ACL重建术后12个月单腿跳测试表现和Tegner活动评分的预测因素。
前瞻性队列研究。
招募91例行ACL重建术的患者。基于ACL重建术后3个月进行的膝关节检查，采用多因素logistic回归分析确定术后12个月单腿跳测试和Tegner活动评分的预测因素。3个月时评估的因素包括Biodex平衡系统前后向和内外侧指数；Y平衡测试前向、后内侧和后外侧伸展距离；膝关节伸肌和屈肌每体重的峰值扭矩；以及膝关节伸肌和屈肌每体重的平均功率。
单腿跳测试中，每体重膝关节伸肌峰值扭矩（PT/BW）和Biodex平衡系统内外侧指数分别以132 N·m/kg和0.45为临界值，被确定为实现肢体对称指数在10%以内的预测因素。此外，Y平衡测试后内侧伸展距离和每体重膝关节屈肌平均功率分别以92.5 cm和122 W/kg为临界值，被预测为Tegner活动评分超过6分的因素。
ACL重建术后3个月，膝关节伸肌峰值扭矩和内外侧平衡可预测12个月评估时单腿跳测试的表现，而动态后内侧平衡和膝关节屈肌平均功率可预测旋转能力。
