[Purpose] The purpose of this study was to provide useful information for future treatments and to organize rehabilitation programs for anterior cruciate ligament injury by assessing isokinetic muscle strength and laxity of knee joints in athletes with anterior cruciate ligament injuries. [Subjects and Methods] Thirty-one high school athletes with anterior cruciate ligament injuries participated in this study. Isokinetic muscle strength at 60°/sec and anterior cruciate ligament laxity for non-involved and involved sides, classified on the basis of the severity of anterior cruciate ligament injury, were assessed. [Results] A comparison of isokinetic muscle strength measured from the non-involved and involved sides showed a significant difference in the maximum strength and knee flexor muscle strength. For laxity, a significant difference was observed in the anterior drawer test results obtained with a force of 88 N. [Conclusion] In conclusion, this study has shown that the assessment of isokinetic muscle strength and ligament laxity from athletes with anterior cruciate ligament injury should be utilized to provide baseline data for prevention and prediction of injury.
[目的] 本研究旨在通过评估前交叉韧带损伤运动员的等速肌力和膝关节松弛度，为未来的治疗提供有用信息，并制定前交叉韧带损伤的康复计划。[对象与方法] 31名患有前交叉韧带损伤的高中运动员参与了本研究。根据前交叉韧带损伤的严重程度进行分类，评估了非损伤侧和损伤侧在60°/秒时的等速肌力以及前交叉韧带松弛度。[结果] 非损伤侧和损伤侧等速肌力测量结果的比较显示，最大肌力和膝关节屈肌肌力存在显著差异。对于松弛度，在施加88 N力时获得的前抽屉试验结果存在显著差异。[结论] 总之，本研究表明，应利用对前交叉韧带损伤运动员的等速肌力和韧带松弛度评估，为损伤的预防和预测提供基线数据。
