title: Revision total hip arthroplasty for pelvic osteolysis with well-fixed cementless cup.
abstract: Treatment of pelvic osteolysis after total hip arthroplasty (THA) remains controversial. Clinical and radiographic outcomes of revision THA were evaluated in 62 hips with pelvic osteolysis and well-fixed cementless cups. The patients' mean age was 50.9 years, and the mean interval from primary to revision THA was 9.7 years. For revision, cementless cups were used in 51 hips, and cemented cups in 11 with acetabular reinforcement rings in 9. The mean duration of follow-up after revision THA was 5.9 years (range, 3.0-9.7 years). At final follow-up, the average Harris Hip Score was 92.4, and there was no radiographic complication except for 1 with change of inclination. Revision THA for pelvic osteolysis with well-fixed cementless cups showed favorable outcomes, and it can be preferentially used in young patients.
