Abstract

Abstract : Background: Periacetabular osteotomy (PAO) is an established treatment for symptomatic acetabular dysplasia, which is a well-recognized 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 patient-reported outcome measures for this population, and the types of adjunctive procedures performed at the time of PAO surgery. Methods: Demographics, disease characteristics, and patient-reported functional measures were prospectively collected from all patients who underwent PAO performed by 12 surgeons from 2008 to 2013. Results: We enrolled 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/m 2 . 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 patient-reported 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.
