Image Processing and Meshing
Three commercially available knee prostheses with different types of tibial post designs were digitized using a Siemens SOMATOM Definition Flash CT scanner. The DICOM files were loaded in Simpleware ScanIP where the metallic femoral component and the polyethylene insert were reconstructed. 3D finite element meshes were created in Simpleware FE using four-node tetrahedral elements, and exported to LS-DYNA for simulation.
