Between 1986 and 1990, we carried out 55 rotational acetabular osteotomies in 54 @entity1 with @entity7195 . Five hips were lost to follow-up. Of the 50 remaining, the degenerative changes were classified according to the criteria of T  nnis as grade 0 in 23, grade 1 in 16 and grade 2 in 11. The mean age of the three @entity1 and 46 @entity1 at the time of operation was 31.8 years (13 to 53). The mean follow-up was 137 months (120 to 174). At the most recent follow-up, 48 @entity1 had satisfactory relief from @entity158 . There was a slight decrease in the range of movement, particularly of flexion, in 18 hips. Radiologically, all osteotomies had united satisfactorily. There was radiological evidence of improvement in degenerative changes in 13 hips (5 grade 1 and 8 grade 2). Ten deteriorated (5 grade 0, 3 grade 1, and 2 grade 2) and one required total hip arthroplasty ten years after osteotomy. The @entity571 in the two hips with an associated @entity14953 progressed. The changes in radiological indices such as the centre-edge angle, acetabular femoral head index, acetabular root obliquity and horizontal or vertical displacement of the femoral head showed no statistical difference (unpaired Student's t-test) between the @entity1 with radiological progression and those with and without improvement.
