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

9809243Hefzy本研究的目的是开发膝关节的三维动态模型，包括胫股关节和髌股关节，并获得实验数据来验证模型预测。 该模型将允许关节面的可变形接触和分段数学表示。 将通过对尸体样本的股四头肌肌腱施加脉冲载荷来模拟下肢动态活动（如踢腿）的实验进行模型确认。 一旦确认，作为首次应用，该模型将用作手术模拟器，以确定髌股疾病常见重建手术后动态股四头肌载荷下的膝关节反应。 这将增加对外科手术如何影响关节或身体部分功能的理解。*

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.***
