Improvements seen after reverse PAO for patients with FAI secondary to acetabular retroversion


At mid- and long-term follow-up, clinical and radiographic results improved among young patients with either isolated retroversion or retroversion and hip dysplasia who underwent reverse periacetabular osteotomy for treatment of femoroacetabular impingement.

Researchers performed a retrospective review to identify 23 patients with femoroacetabular impingement secondary to acetabular retroversion and treated with reverse periacetabular osteotomy. Of the 30 hips, 10 had retroversion and dysplasia and the remaining had isolated retroversion. Preoperatively and at the last follow-up, investigators evaluated patients’ radiographs and Harris hip scores (HHS). The average follow-up for the study was 5 years.
