A sagittal plane model of knee joint based on crossed-four-bar-linkage-based tibiofemoral joint model has been developed using geometric and force equilibrium constraints. The model predicts and explains the movement of contact point on the patella and femur, variation of patellar and patellar tendon angle, variation of patellar mechanism angle and variation of patellofemoral contact force and patellar tendon force. The computed results agree well with the published experimental results.
基于交叉四杆连杆式胫股关节模型的膝关节矢状面模型已利用几何和力平衡约束条件开发出来。该模型可预测并解释髌骨与股骨上接触点的运动、髌股角和髌腱角的变化、髌股机制角的变化以及髌股接触力和髌腱力的变化。计算结果与已发表的实验结果吻合良好。
