An Algorithmic Approach to Surgical Decision Making in Acetabular Retroversion

60 hips in young adult patients with symptomatic femoroacetabular impingement with radiographic evidence of acetabular retroversion (crossover sign on AP radiograph or retroversion on MRI/CT)

Treatment algorithm using measurements of acetabular coverage and cartilage condition to direct either periacetabular osteotomy (n=30) or surgical dislocation and osteochondroplasty of the femoral head-neck junction and acetabular rim (n=30)

Harris Hip Score, overall survivorship, and radiographic correction (elimination of crossover sign and correction of posterior wall sign)patient reported
