P193 - Short-term Outcomes of Primary Labral Reconstruction in Patients with Femoroacetabular Impingement, Labral Tears, and Chondral Defects
Abstract
Purpose
To determine if there are any benefits associated with labral reconstruction (RECON) relative to labral resection (RESEC) in the presence of severe acetabular cartilage defects.
Methods and Materials
Prospectively collected data between August 2008 and July 2016 were retrospectively reviewed. Inclusion criteria were hip arthroscopy, acetabular Outerbridge grade III /IV, irreparable labral tears that underwent RECON or RESEC, and minimum 2-year postoperative measures for the modified Harris Hip Score, Non-Arthritic Hip Score, Hip Outcome Score–Sports Specific Subscale, International Hip Outcome Tool, Patient Satisfaction, and Visual Analogue Scale. Exclusion criteria included Tönnis grade>1, previous hip conditions, or previous ipsilateral hip surgeries. A 1:1 matched-pair analysis was performed based on age ±5 years, sex, body mass index ±5 kg/m2, Tönnis grade, acetabular microfracture, femoral Outerbridge grade (0 or I compared with II, III, or IV). Relative Risk (RR) and conversion rate to total hip arthroplasty (THA) were calculated.
Results
34 RECON hips were successfully matched. Both groups demonstrated significant improvements in patient-reported outcomes (PROs). THA conversion was 8.8% and 29.4% for the RECON and RESEC groups, respectively (P=0.03). RECON was over three times less likely to require THA conversion than the RESEC group (RR = 3.33; 95% CI = 1.005-11.05).
Conclusion
In the setting of primary arthroscopic management of FAI, irreparable labral tears, and acetabular chondral lesions of Outerbridge III/IV, patients that underwent RECON and RESEC experienced significant improvement in PROs at minimum 2-year follow-up, and these functional scores were comparable when groups were matched. However, RR and rate to THA conversion were significantly higher in the RESEC group.
