Abstract

Background: Periacetabular osteotomy (PAO) is an established treatment for symptomatic acetabular dysplasia, which is a wellrecognized cause of hip pain, functional limitations, and secondary osteoarthritis. The purpose of this study was to describe the demographics of patients undergoing PAO, the baseline patientreported outcome measures for this population, and the types of adjunctive procedures performed at the time of PAO surgery. Methods: Demographics, disease characteristics, and patientreported functional measures were prospectively collected from all patients who underwent PAO performed by 12 surgeons from 2008 to 2013. Results: Weenrolled 950 consecutive patients (982 hips) in the study; 83% were female and 17% were male, with an average age of 25.3 years and an average body mass index (BMI) of 24.6 kg/m2. Most patients were Caucasian (87%), and 15%had undergone previous hip surgery. Before PAO was performed, most patients had had symptoms for 1 to 3 years. Baseline modified Harris Hip and University of California Los Angeles activity scores (61.8 and 6.6, respectively) indicated that patients had considerable functional limitations. Discussion: Patients undergoing PAO for symptomatic dysplasia were predominantly young, female, and Caucasian with a normal BMI. Many patients had undergone prior hip surgery, and most had had symptoms for several years before treatment. Baseline patientreported functional scores demonstrated marked functional limitations. Adjunctive procedures for intra-articular pathology, especially femoral osteochondroplasty and hip arthroscopy, are commonly performed at the time of PAO.
