Hip joint modelling for orthopaedic application
Computational models of muscle forces are critical in the design of total joint replacements. They allow a wide range of loading and boundary conditions and geometries to be rapidly tested, and assess implant function and vulnerability to loosening.
There is a trade-off between the level of model detail and the run-time of the model. Numerical experiments studying patient and surgical variability require many runs of many permutations, so detailed models such as finite element models are not often directly used to generate results for these experiments.
We are developing a surrogate modelling approach to capture much of the detail of a realistic finite element model of the hip joint muscles, incorporating active contraction, broad attachment sites, and realistic fibre directions, but which can run in a short time similar to line-segment models.
