Summary: Arthroscopic Reconstruction of Segmental Defects of the Hip Labrum: Results in 22 Patients with Minimum Two-Year Follow-up with Comparison to a Matched Control of Labral Repair.

Abstract:
Background: The aim of labral reconstruction is to restore labral function in the setting of insufficient tissue for repair. Purpose: The purpose of this study was to report on minimum two-year outcomes of patients who had undergone arthroscopic reconstruction of the hip labrum for segmental defects with respect to a matched control who had undergone labral repair. Methods: Data was collected on all patients undergoing hip arthroscopy during the study period from April 2008 to April 2013. All patients who had undergone arthroscopic labral reconstruction with either hamstring allograft or autograft were included. This group was matched in a one to two ratio with a control that had undergone labral repair according to age within 3 years, sex, body mass index categories, Tonnis grade and capsular treatment. The following outcomes were recorded in each group: Four patient reported outcome scores (PROs), Visual Analogue Scale (VAS) for pain, patient satisfaction, revision hip arthroscopies and conversion to total hip arthroplasty (THA). Results: 1412 patients underwent hip arthroscopy during the study period of which 22 patients had labral reconstructions and 833 patients had labral repair. 22 (100%) labral reconstruction and 719 (86.4%) labral repair cases had two-year follow-up. Both the study and control groups demonstrated significant improvement in all PROs. Mean patient satisfaction was 6.73 and 7.76 for the study and control groups respectively. There was no significant difference in the magnitude of change in any of the PROs in between groups. There were no post-operative complications in each group. Both groups had a low incidence of secondary procedures and there was no significant difference with respect to conversion to THA and revision arthroscopy. Conclusion: Arthroscopic labral reconstruction is a safe and effective procedure for the treatment of segmental deficiencies of the labrum. It is associated with a significant improvement in patient reported outcomes with a low incidence of secondary surgery within two-year follow-up. Improvements in PROs, VAS, patient satisfaction and incidence of secondary procedures were comparable to a match control treated with labral repair. However, longer-term follow-up is needed to determine if these results persist.
