A model of the knee in the sagittal plane was used to investigate the ligament forces resulting when an external load applied to the tibia resisted either extension or flexion of the knee under increasing isometric quadriceps or hamstrings contractions, respectively. An elementary mechanical analysis showed which ligament, the anterior or posterior cruciate, was loaded at a given flexion angle and known line of action of the external load. Ligament force, as a proportion of the external load, was also calculated. The results serve as guidelines for the design of injury-specific physical therapy techniques for use after cruciate ligament reconstruction.
在矢状面建立膝关节模型，以研究当分别在等长股四头肌或腘绳肌收缩增强的情况下，施加于胫骨的外部负荷抵抗膝关节伸展或屈曲时所产生的韧带力。基本力学分析表明，在给定的屈曲角度和已知外部负荷作用线的情况下，前交叉韧带或后交叉韧带中的哪条韧带承受负荷。还计算了韧带力占外部负荷的比例。这些结果为交叉韧带重建术后使用的特定损伤物理治疗技术的设计提供了指导。
