EP1.14 Arthroscopic Primary Labral Reconstruction in the Hip: Minimum 10-Year Outcomes with a Nested Propensity-Matched Control

Background: While labral reconstruction has shown promising short- and mid-term benefits in addressing irreparable labral tears, there remains a notable lack of evidence regarding its long-term-outcomes.

Purpose/Hypothesis: To present minimum 10-year patient reported outcomes (PROs) of primary arthroscopic reconstruction in the setting of irreparable labral tears in comparison to a matched labral repair group. Primary labral reconstruction is anticipated to demonstrate comparable improvement in PROs when contrasted with the control group.

Study Design: Retrospective Cohort

Methods: Data from February 2008 to December 2013 was retrospectively reviewed. Patients were included if they underwent hip arthroscopy for segmental labral reconstruction in the setting of irreparable labral tear and femoroacetabular impingement, with minimum 10-year follow-up for modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score–Sports Specific Subscale, patient satisfaction, and visual analog scale for pain. Exclusion criteria were Tonnis osteoarthritis grade >1, prior hip conditions, or workers’ compensation claims. Cases were matched in a 1:3 ratio with a greedy nearest neighbor algorithm with a caliper of 0.2. Patient-reported outcomes and rates of achieving clinically relevant thresholds were compared between the two groups.

Results: 22 Hip (22 patients) who underwent primary labral reconstruction were 1:3 matched to 66 hips (63 patients) who underwent primary repair. At minimum 10-year follow-up both groups showed significant improvement in all PROs and VAS with comparable rates of improvement. Both cohorts achieved MCID and PASS at similar rates for mHHS, NAHS, and HOS-SSS. Patients who underwent primary repair achieved SCB for NAHS at a significantly higher rate.

Conclusions: Hip arthroscopy with segmental labral reconstruction resulted in significant improvement in PROs at minimum 10-year follow-up and reaches comparable functional outcomes when compared with a benchmark labral repair control group.
