This study was conducted to analyze the clinical and radiographic results of isolated acetabular revisions during which intact femoral stems were retained. Twenty-nine hips of 26 patients who were followed up for a minimum of 3 years were examined. The average time from primary operation to revision surgery was 9.2 years, and the average follow-up time after revision was 5 years. The average Harris hip scores improved from 56.4 to 89.8 points after revision surgery, and in all cases, the acetabular components and femoral stems were assessed as stable at the final follow-up. The average length of service of the femoral components was 14.2 years. In conclusion, we recommend that isolated acetabular revision be considered in cases with an acetabular component failure and a stable femoral component.
