Research project: Combined musculoskeletal and finite element modelling of total hip replacement to account for surgical and patient related factors

Currently Active: 

In this project, muscle and hip contact forces were predicted using a musculoskeletal model, which was then combined with a finite element model to calculate primary stability in a cementless total hip replacement stem. Similarities were found between the kinematics measured in the healthy subjects from this study and measurements published in the literature. The predicted hip contact forces were also similar to measured hip forces in the literature.

Once this basic verification was complete, the new combined modelling tools were used to investigate surgical and patient-related variability. The applied muscle-loads were varied to simulate the range of observed patient loading conditions, and compare pre- and post-operative loading profiles. This lays the groundwork for better integrated modelling of patient variability in future studies.
