N2 - We are reporting squeaking in a ceramic on ceramic hip prosthesis. At revision neck-socket impingement was found with notching of the femoral neck. The cup was modified which resolved the component impingement and squeaking. The position of the cup was 30 degrees of planar anteversion and 55 degrees inclination. In this case, the cup positioning and design were suboptimal creating impingement. Squeaking occurred as a result of neck-socket impingement. Hard on hard bearing systems may be less forgiving without the polyethylene "bumper." Attention should be given to optimizing component positioning: consider using a navigational system. Cup designs that maximize range of motion should be used.
