Abstract
We measured the change of the center of hip rotation after the revision of acetabular loosening using an acetabular reconstruction ring and an impaction allogenic bone grafting. Thirty-five revision total hip arthroplasties were performed. The average follow-up was 3.8 years. Horizontal distance was changed from 34.01 ± 10 mm preoperatively to 41.07 ± 6 mm at the latest follow-up. Vertical distance was changed from 32.06 ± 9 mm preoperatively to 20.21 ± 7 mm at the latest follow-up. The Harris hip score was improved from an average of 47 in the preoperative period to 86 at the final follow-up. The restoration of the anatomical hip center has shown to be favorable in terms of functional and radiologic evaluation in total hip revision.
