Functional outcome in adult patients following Bernese periacetabular osteotomy

This study evaluated functional outcome following Bernese periacetabular osteotomy. In 24 patients with mean follow-up of 3.5 years, mean dysfunction score was 15.23 on the Short Musculoskeletal Function Assessment. Eighteen patients (75%) scored = or <20, indicating a high functional level. Irrespective of preoperative Shenton line continuity, most patients demonstrated a high functional level. However, a trend toward a poorer outcome was observed in patients with preoperative noncongruent joints and Tonnis osteoarthritis grade 3. These results suggest patients with less than optimal presentation may still benefit from this surgery, delaying or eliminating the need for total hip arthroplasty.
