本研究的主要目的是通过建立人体膝踝足有限元模型量化膝关节结构在行走过程中对于不同足底支撑的生物力学响应。以外侧楔形鞋垫为例，利用步态分析获取肌肉模型和有限元模型的输入条件，通过肌肉模型计算得出的肌肉力进一步定义有限元模型在各个足底支撑作用下的肌肉加载边界条件。有限元仿真结果表明外侧楔形鞋垫减小了内侧半月板和股骨关节软骨处的接触压强。

The primary objective of this study is to establish a comprehensive ifnite element model of the human knee–ankle–foot to quantify the biomechanical responses of knee structures to various foot supports in gait. Laterally wedged insoles (LWI) were fabricated for interventions. Gait analyses were performed to obtain input information for the muscle model and ifnite element model. Muscle model was also applied to provide muscle loading boundaries in each foot support condition for the ifnite element model. The simulation results indicated that LWI diminished the contact pressure at the medial meniscus and femoral cartilage.
