Abstract The hip is a ball and socket joint designed to bear the body mass as well as for facilitating the movement in many directions. Hip replacement is an operation to replace a natural hip joint with an artificial one. The aim of the present work is to conduct a parametric study that comprises the parameters affecting the strength of hip‐joint cement fixation (offset distance and ball diameter), in order to come‐up with the best combination for maximum strength. The results lead to recommending offset distance (3–6 mm) and ball sizes (34 and 50 mm) for maximum cement strength.
