The purpose of this study was to evaluate whether knee anterior laxity changes after anterior cruciate ligament injury and surgery are related to aspects of thigh muscle resistance training during rehabilitation.
Forty-nine subjects (13 females) diagnosed with an anterior cruciate ligament-deficient knee or who had undergone anterior cruciate ligament reconstructive surgery participated in this study. The subjects trained their knee extensors in the open kinetic chain during a 6-wk program, and the relationship of aspects of training (for example, absolute resistance load) and other factors to anterior laxity change during this period were analyzed using linear regression analysis.
The only factor found to be significantly related (r = -0.347) to anterior knee laxity change was average absolute load used in training the knee extensors.
These results offer some early clinical support for increasing the strain on the anterior cruciate ligament graft (in patients treated with reconstruction) or other passive restraints to anterior tibial displacement, during rehabilitation after anterior cruciate ligament injury and reconstruction surgery to promote decreased knee anterior laxity.
本研究旨在评估前交叉韧带损伤及手术后膝关节前向松弛度的变化是否与康复期间大腿肌肉抗阻训练的各方面相关。
49名受试者（13名女性）参与了本研究，他们被诊断为前交叉韧带损伤的膝关节，或接受了前交叉韧带重建手术。受试者在为期6周的项目中进行开链运动的膝关节伸肌训练，并使用线性回归分析来分析训练的各方面（如绝对阻力负荷）及其他因素与该期间前向松弛度变化的关系。
发现与膝关节前向松弛度变化显著相关（r = -0.347）的唯一因素是训练膝关节伸肌时使用的平均绝对负荷。
这些结果为在前交叉韧带损伤和重建手术后的康复过程中，增加前交叉韧带移植物（接受重建治疗的患者）或其他限制胫骨前移的被动约束上的应变以促进膝关节前向松弛度降低提供了一些早期临床支持。
