184 patients were randomized to examine the potential of large femoral heads in decreasing the dislocation rate following revision total hip arthroplasty (THA). Patients received either a standard head (32 mm) or a large head (36 or 40 mm), and were assessed at a mean follow-up of 5 years for dislocation and 2.2 years for quality of life (QOL). Results indicated that dislocation rates were lower in patients who received the large head, while there was no difference in QOL between the two groups.
