Boolean operations were used for inserting the spherical cemented component. Cemented component was eccentrically inserted into the pelvic bone and that created imperfection as non-uniform cement layer. Two contacts were defined in the FE model. The first contact is defined between the cement layer and the pelvic bone and the second one is between the cement layer and the polyethylene cup. The model was loaded by quasi–static joint forces, representing the maximum value of stance phase of gait [Bergmann et al., 2001]. The FE model was used to ascertain the contact stress conditions in the underlying subchondral bone.
