Design and optimisation of patient-specific porous femoral stems

Based on patient-specific computational models, the porous region of the stems influenced the reduction of stress shielding compared to fully solid stems. Considering implant fatigue failure and bone-implant micromotion, the PP and SS templates were found to be the most suitable design approaches to address femoral bone stress shielding after total hip replacement. Further investigation is required to fully comprehend the implications of porous femoral stems on long-term implant stability.
