Geometry Reconstruction and Finite Element Modelling of Porcine Knee Joint
Abstract
Arthritis is a leading cause of disability in North America. It is believed to be associated with the abnormal contact mechanics of articular cartilage. Contact analyses are widely used to determine the mechanical interplays among the different tissues in the joint. Animal joints are often used to validate a computational model and understand human joint mechanics.
The objectives of this research are to construct the geometry of the porcine stifle joint using a combined CT and automated indentation mapping method, and build a finite element model in ABAQUS to determine the joint mechanics.
The porcine knee joint model were reconstructed using MATLAB and Rhinoceros. A knee compression was simulated with ABAQUS, which considered fluid pressure and flow in articular cartilages and menisci. The reaction predicted by the model generally agrees with the measurements from laboratory tests, which partially validates the modelling methodology.
