Finite element predicted fracture strength at distal femur and proximal tibia under biaxial loading

CT-based finite element (FE) modelling can be used to assess bone fragility around the knee after spinal cord injury (SCI), but models must be validated using realistic loading scenarios. Activities such as wheelchair transfer are likely associated with biaxial loads (e.g., compression + torsion), however no published FE models have been validated under these conditions. In this work, we adapted a previously developed FE workflow and assessed its accuracy in predicting fracture strength of the proximal tibia and distal femur under biaxial loading.
