ABSTRACT
PURPOSE:
To evaluate implant survivorship and clinical outcomes after acetabular revision using cementless acetabular cups. MATERIALS ANDMETHODS:
We evaluated 27 cementless acetabular revision cases performed between January 1998 and October 2005. All patients were followed up for more than 2 years, and the mean follow-up period was 54.1 months (range 24~120 months). In all cases, morselized allografting was performed. Five cases needed structural allografting to achieve stability of the acetabular cup. The clinical results were analyzed using the Harris hip score, and radiological analysis was performed for evaluation of radiolucent lines, osteolysis, loosening, and changes in the hip center.RESULTS:
At the time of latest follow-up, no cups showed failure requiring re-revision. The average Harris hip score improved from 67.1 points preoperatively to 91.4 points postoperatively. Radiologically, 7 cases (25.9%) showed radiolucent lines around the acetabular cup, but there was no loosening or osteolysis.CONCLUSION:
Cementless acetabular revision showed satisfactory radiological and clinical results on short-term follow-up analysis. Even in cases with considerable amounts of acetabular bone loss, stable fixation could be obtained with structural bone grafting.
