Isolated acetabular revision can be associated with variable patient outcomes; there is a risk of hip instability. We evaluated 42 isolated acetabular revision operations and investigated the impact of patient age, diagnosis, bone stock, bone loss, bone augmentation, and obesity on pain and the Harris hip score. Preoperative radiographs were graded according to Paprosky et al. Postoperative radiographs were graded according to Moore et al. and for implant position, prosthetic fixation, and osteolysis. Complications, patient outcome, reoperations, and acetabular rerevisions were recorded. All patients had complete clinical and radiographic followup with a minimum followup of 2 years (mean, 6.4 years; range, 2-13 years). The mean pain score and the mean Harris hip score improved postoperatively. There was one infection 6 months after operation. There were no dislocations. There were three acetabular rerevisions (7%) for aseptic loosening. Patient age, preoperative diagnosis, bone loss, and pelvic bone augmentation had no influence on pain or Harris hip scores. Before operation, obese patients tended to have less pain than nonobese patients but at followup obese patients had less improvement in pain scores than nonobese patients. Level of Evidence: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.
