Analysis, Modeling and Experimental Validation of the Three-Dimensional Dynamic Response of the Human Knee Joint

本研究的目的是建立一个包含胫骨-股骨关节和髌股关节的膝关节三维动力学模型，并获得实验数据以验证模型的预测。该模型将允许可变形接触和关节表面的分段数学表示。模型验证将通过对身体标本的股四头肌肌腱施加脉冲载荷来进行实验，以模拟腿部的动态活动，如踢腿。一旦得到验证，作为第一次应用，该模型将被用作手术模拟器，以确定在常见的派特罗-股骨疾患重建手术后，在动态股四头肌负荷下的膝关节反应。这将增加对外科手术如何影响关节或身体节段功能的理解。

The model will allow deformable contact and piecewise mathematical representation of the articular surfaces. Model validation will be conducted by performing experiments that simulate dynamic activities of the lower limb, such as kicking, by applying impulsive loads to the quadriceps tendon of cadaveric specimens. Once validated, and as a first application, the model will be utilized as a surgical simulator to determine the knee response under dynamic quadriceps loading following common reconstruction procedures for patello-femoral disorders. This will increase the understanding of how the function of a joint or body segment can be affected by a surgical procedure.***
