9809243HefzyThe objective of this research is to develop a three-dimensional dynamic model of the knee joint to include the tibio-femoral joint and the patello-femoral joint, and to obtain experimental data to validate the model predictions. 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.***

本研究的目的是建立包括胫骨-股关节和髌骨-股关节在内的膝关节三维动力学模型，并获得实验数据来验证模型的预测。该模型将允许关节表面的可变形接触和分段数学表示。模型验证将通过进行模拟下肢动态活动的实验来进行，例如通过对尸体标本的股四头肌肌腱施加脉冲载荷来踢脚。一旦验证，作为第一次应用，该模型将被用作外科模拟器，以确定髌骨-股骨疾病常见重建手术后动态股四头肌负荷下的膝关节反应。这将增加对关节或身体部分的功能如何受到外科手术影响的理解
