This Matlab tool can be used to generate OpenSim musculoskeletal models with personalised femoral neck-shaft and anteversion angles, as well as tibial torsion angles.

More info about the tool can be found in the paper published in Journal of Biomechanics: https://doi.org/10.1016/j.jbiomech.2021.110589.
