الملخصCementless hip prostheses are commonly used to repair the femur bones. The primary stability of the hip prosthesis highly dependent on the peri-prosthetic bone ingrowth into the porous structure which is influenced by mechanical and biological environments. 3D finite element models of homogenous and functionally graded porous structures were designed to estimate the bone ingrowth using mechano-regulation algorithm. 200 µm and 800 µm pore spacing for homogenous structures were used, however, for functionally graded structures, the pore spacing was increased and decreased linearly across the length between 200 to 800 µm. Bone ingrowth were simulated using 25 µm micromovements which was determined from macro models. Functionally graded decreasing porous structure showed the highest bone ingrowth 98% with the most uniform tissues distribution.
