We report the short-term results of revision of cemented acetabular component to cementless acetabular component in 15 patients (15 hips) between 1997 and 2000. The mean follow-up period was 3.2 years (range : 2 to 5.6). There were two males and thirty-three females. Their mean age was 67 years (range : 60 to 77). The mean period between primary THR and revision THR was 9.9 years (1.8 to 19.5). The cause of revision was aseptic loosening in all cases. Acetabular deficiency was graded according to classification of AAOS : 12 hips were type II and three hips were type III. Only the acetabular component was revised in nine hips and both acetabular and femoral components in six hips. Eight hips underwent bone graft. Clinical and radiographical evaluation were performed. All but one hip were good results. One acetabular component was revised for aseptic loosening.
