The problem of the damage of the bioimplants is very important today. In the endoprosthesis surgery there is a large percentage of implant defects, which cause the failure of the whole prosthesis. One kind of the total hip replacement functionality loss is acetabular cup pull-off from pelvis bone. This paper is aimed at manufacture perturbations (shape deviations) analysis as one of the possible reasons to this kind of failure. Dimension and of geometry manufacturing perturbations (roundness) were analyzed in detail. It was found, that these perturbations affect considered values of contact pressure and frictional moment. Contact pressure and frictional moment are quantities affecting replacement success and durability.
