In this contribution, an approach on the mechanically stimulated osseointegration of hip joint endoprostheses considering load cases of daily movements is presented. The mechanical behavior of the bone‐implant interface is modeled with a material model adopted from computational plasticity. Under consideration of a detailed analysis of the interface conditions, limiting factors for the osseointegration process are identified and the bone ingrowth prediction is performed.
