Abstract
ABSTRACTTo report the operative findings and outcomes of hip arthroscopy for recurrent pain following periacetabularosteotomy (PAO) for acetabular dysplasia. A departmental database was used to identify patients who underwenthip arthroscopy following PAO between 2000 and 2009. Demographic data, arthroscopic findings, functional out-come scores and patient satisfaction were analysed. Of 556 PAO patients, 17 hips in 16 patients (3.1%) under-went post-PAO hip arthroscopy. Mean age at PAO was 23.8 years, and mean age at arthroscopy was 27.0 years.Common hip arthroscopy findings included labral tears (13 hips, 81.3%), significant (grade 2) chondral changes(12 hips, 75%), cam impingement (7 hips, 43.8%) and pincer impingement (6 hips, 37.5%). At mean follow-up2.8 years after arthroscopy, additional procedures had been performed in six hips (37.5%), including total hiparthroplasty in one hip. Post-PAO arthroscopy questionnaire revealed 85.7% of patients with improved hip pain,57.1% improved hip stiffness and 57.1% improved hip function. There was no significant difference in functionaloutcome measures. Common post-PAO hip arthroscopy findings include labral tears, chondral changes and femo-roacetabular impingement. Many patients reported subjective hip improvement from post-PAO arthroscopy, buthip outcome scores were unchanged and one-third of patients had further surgery.INTRODUCTION
