We present two cases of infected primary total hip replacements (THR) where only one of the two components exhibited loosening. Both were revised using a two stage, one component revision technique, replacing the loose component only. In the first case the acetabular component was revised leaving the original femoral stem in situ. In the second case, the femoral component was revised, leaving the original acetabular cup undisturbed. Both patients remained infection free at three and half and three years follow up respectively.
