 We report eight cases of total hip arthroplasty after earlier rotational acetabular osteotomy. All of the patients were women,and their mean age at the time of the total hip arthroplasty was 55 years old (range:51~61 years old). The mean duration of follow-up was 4.5 years. Clinical,radiological,and intraoperative evaluations were performed. All patients had a good clinical JOA score at the most recent follow-up but their range of motion of the hip was poor. CT images can supply useful information regarding good acetabular cup orientation,and proper resection of acetabular osteophytes is necessary.
