The purpose of this study was to obtain lines of action and moment arms in the sagittal plane of the major force-carrying structures crossing the knee joint. The muscles and ligaments studied were the quadriceps, biceps femoris, semimembranosus, and semitendinosus muscles and the anterior and posterior cruciate and medial and lateral collateral ligaments. All lines of action and moment arms of the structures of interest were determined as a function of knee joint angles and were expressed using polynomial regression equations. This representation of the results allows for easy application of the findings to musculoskeletal models of the human knee joint.
本研究的目的是获取在膝关节矢状面内穿过膝关节的主要承重结构的作用线和力臂。所研究的肌肉和韧带包括股四头肌、股二头肌、半膜肌和半腱肌，以及前交叉韧带、后交叉韧带、内侧副韧带和外侧副韧带。所有感兴趣结构的作用线和力臂均根据膝关节角度确定，并使用多项式回归方程表示。结果的这种表示方式便于将研究结果应用于人体膝关节的肌肉骨骼模型。
