Abstract
We carried out and observed the results of RAO in 44 hips (41 cases). Overall results were generally satisfactory. For advanced stage and end stage cases, we performed excessive rotation of acetabulum and also varus osteotomy on a wider range of indications. In cases of patients over 50 years old there can be some problems with rehabilitation, however RAO could be carried out in some of our cases (unilateral, involvement advanced cases without marked deformity). In addition, coxa plana-vara trochanterica were treated by RAO with additional procedure. A pre-operative arthrogram using the positions of abduction and pelvic anterior tilt was useful for estimating postoperative joint congruity.
