Lower extremity muscle forces in abnormal gait and their improvement after total hip arthroplasty (THA) in hip osteoarthritis are closely related to the gait motion and disease seriousness. Therefore, subject-specific prediction is necessary to assess joint reaction forces, muscle forces and stress distribution of bone around the hip. To achieve this, a workflow with the AnyBody Modeling System (AMS) in combination with Mechanical Finder (MF), a popular software made in Japan specialized for finite element analysis (FEA) of bone reflecting heterogeneous material properties, was established.
In this webcast, we will show a change in stress distributions of femur in the gait motion of a hip osteoarthritis patient before and after THA.
