The purpose of this study is to identify the incidence of capsular defects in patients undergoing revision hip arthroscopy.A radiographic and anatomical analysis of MR arthrograms of patients undergoing revision arthroscopy was performed to assess for the presence of capsular defect. Intra-operative images and findings were reviewed. Patients with persistent cam and pincer lesions were excluded.From October 2011 to October 2012, 25 patients underwent revision hip arthroscopy surgery, and 9 patients met our inclusion criteria. Within this series, all patients had post-surgical capsular irregularities and seven patients (78 %) had radiographic evidence of capsule and iliofemoral defects on MR arthrogram. Gross capsular defects were confirmed at revision surgery in two patients.The findings of this study demonstrate post-surgical radiographic and anatomical evidence of capsular defects in a select group of patients following hip arthroscopy.IV.
