Skeletal Geometry Analysis
Three-dimensional bone registration based on a template model using Matlab and Visualization Toolkit (VTK).
Anatomical landmarks and bone morphology prediction of a femoral model based on local region matching algorithm using Matlab and VTK.
Automatic Bernard quadrant method and a manual GUI program for localizing the ACL insertion point using Matlab and VTK.
Total knee replacement - TKA automatic positioning
Predict automatically the anatomical landmarks and regions in distal femur and proximal tibia.
Measure the bone morphology of the knee joint and and build the anatomical coordinate system automatically.
Position the total knee arthroplasty (TKA) for reconstruct the knee joint mechanical axis.
The approach can be applicable for total hip replacement. In the future, the method can be combined with human skeletal kinetics simulation to find the optimal TKA position that recover the knee kinetics for patients.
