Outcomes After Hip Labral Reconstruction Using Peroneus Longus Graft: A Novel Graft Experience.

Currently, there is no consensus on the ideal graft for hip labral reconstruction. The purpose of this study was to describe the surgical technique and report the short-term outcomes after hip labral reconstruction using a peroneal longus allograft. Eleven patients diagnosed with femoracetabular impingement and irreparable damage to the acetabular labrum underwent labral reconstruction with a peroneus longus allograft. The average follow-up time was 227 days (range: 26-457 days). Pre-operative radiographic measurements included an average pre-operative center edge angle of 29.0° (range: 19° to 37°) and an average alpha angle of 62.9° (range: 55° to 71°). All patients underwent femoroplasty, with additional procedures including 7 acetabuloplasties and 6 microfractures. The average visual analogue score for pain improved from 4.91±2.17 preoperatively to 3.85±2.0 postoperatively but this was not significant (P=.26). No patients sustained post-operative complications or allograft failures during follow up. Compared to other acetabular labral reconstruction options, the strength and shape of thedcd peroneus tendon may best replicate the native hip labrum. The current findings of no immediate post-operative complications or early failures suggests the peroneus longus allograft may be a viable option for hip labrum reconstruction.
