Allograft Use in Arthroscopic Labral Reconstruction of the Hip With Front-to-Back Fixation Technique: Minimum 2-Year Follow-up.

PURPOSE To present minimum 2-year outcomes in patients who underwent a modified technique for arthroscopic labral reconstruction using iliotibial band allograft tissue and a front-to-back fixation. METHODS From April 2011 to July 2012, all consecutive arthroscopic labral reconstruction patients were included in this Institutional Review Board-approved, prospective case series study. Inclusion criteria were arthroscopic iliotibial band allograft labral reconstruction performed by a single surgeon, age ≥16 years at the time of arthroscopy, and a minimum of 2 years of follow-up. Patients completed subjective questionnaires both preoperatively and postoperatively, including Modified Harris Hip Score (MHHS), the Lower Extremity Function Score (LEFS), Visual Analogue Scale (VAS) pain scores, and patient satisfaction. A modified front-to-back fixation technique for labral reconstruction was used. RESULTS One hundred fifty-two hips (142 patients) met the inclusion criteria for this study; 131 hips (86.2%) had complete follow-up at a minimum of 2 years, and 21 hips (13.8%) were lost to follow-up or had incomplete data during the study period. Seventy hips had concomitant procedures performed; 27 microfracture, 30 chondroplasty, 26 psoas release, 5 os acetabuli resection, and 3 Ganz osteotomy. Overall, 18 hips (13.7%) required revision procedures at a mean of 17 months (range, 1 to 37 months) after the labral reconstruction. In the remaining 113 hips, there was significant improvement in all outcome measures from preoperative to most recent follow-up (P < .0001). The mean MHHS improved by 34 points (P < .0001), and the mean LEFS improved by 27 points (P < .0001). The mean VAS pain score improved by 3 points at rest (P < .0001), 4 points with average pain with daily activities (P < .0001), and 5 points with sport (P < .0001). Patients reported an overall satisfaction of 9 (range, 1 to 10). CONCLUSIONS Arthroscopic iliotibial band allograft labral reconstruction of the hip shows promising outcomes at minimum 2-year follow-up. LEVEL OF EVIDENCE Level IV, therapeutic case series.
