High rate of graft integration after acetabular labral reconstruction with the knotless pull-through technique.

Abstract

Acetabular labral reconstruction has proven to be a good option for treatment of irreparable labral tears. The purpose of this manuscript is to demonstrate the graft integration in patients who undergo acetabular labral reconstruction with use of allograft. Data were prospectively collected on patients undergoing hip arthroscopy between September 2008 and June 2023 and retrospectively reviewed. The inclusion criteria were patients who underwent hip arthroscopy with labral reconstruction and subsequently underwent a second look arthroscopy for revision surgery. The quality of the integration of the graft used in the previous labral reconstruction was examined by analysing pictures taken during the revision arthroscopy procedure. Three different characteristics of the labral graft were assessed: graft integrity, chondrolabral junction restoration, and anastomosis. There were 12 hips (11 patients) who had labral reconstruction performed in the index surgery with either labral debridement or no labral treatment performed in the revision surgery. There were six females and five males with a mean age of 35.3 years. The mean body mass index was 25.7. The average time between surgeries was 29.5 months. Ten out of 12 hips (83%) were found to have good quality of the graft integrity, with 11 out of 12 labral reconstructions (92%) achieving chondrolabral junction restoration and good anastomosis. Acetabular labral reconstruction demonstrated graft integration at a very high rate. Based on these results, labral reconstruction seems to be a biologically reliable option for irreparable labra with the ability to restore the labral anatomy.
