Visualising menisci-femur contact using deformable knee models

Abstract

Computational simulation can help improve our understanding of the knee biomechanics and orthopedic practice. However few computational knee models include a patient specific deformable menisci model. We present two new methods for simulating and visualising menisci-femur contact area during gait cycles, using patient specific knee models and motion data. Specifically we propose a template based 3D model reconstruction method that generates patient specific knee models. We also propose a new deformable menisci model for real-time applications. Our deformable model combines physics-based deformation and spatial deformation, making it easier for users to balance the physical realism and performance needs.
