Finite element analysis reveals the role of design parameters on bone ingrowth in porous hip stems, suggesting improvements in implant stability.

To evaluate how variations in design parameters of a hip stem affect bone ingrowth.
Developed finite element macromodels based on design of experiment approach.
Simulated loading conditions of normal walking and stair climbing using ANSYS.
Incorporated a mechanoregulatory algorithm into bone ingrowth predictions.
Significant bone ingrowth predicted (32%-72%) in proximal regions within the first month post-surgery.
Fibrous tissue ingrowth ranged from 0.5% to 3.5% across all submodels.
Higher pore size and specific core designs resulted in improved elastic modulus of the newly formed tissue.

Loha et al. (2025) studied this question.
