Past projects
Hip
- The application of probabilistic methods for assessment of hip replacement integrity
- Probabilistic analysis of interface failure in total hip replacement
- Patient specific numerical analysis of the resurfaced femoral head
- The initial stability of short stemmed minimally invasive hip replacement components
- Preclinical analysis of cemented medical devices using non destructive evaluation techniques
These models of the proximal femur were generated from a standard CT scan. We use algorithms to apply bone material properties from the CT data, allowing us to perform patient specific analyses.
Knee
- Development of functional assessment tools to evaluate the preclinical performance of a novel knee hemi arthroplasty device
- Determining the optimal mechanical requirements for early intervention devices in the knee
- Computational simulation of wear in total knee replacement
- Effects of femoral component and tibial insert alignment on patellar kinematics in total knee replacement
- The ability of tibial component selection to protect cancellous bone in minimally invasive unicondylar knee replacement
The contours on this image of a knee prothesis represent wear patches predicted by one of our wear alogorithms. They match well with components that have been removed from patients due to excessive wear. The comuptational simulation is a useful preclinical test for new devices.
