Abstract

Femoroacetabular impingement syndrome (FAIS) is commonly associated with acetabular labral tears. Correction of impingement morphology and suture anchor repair of labral tears have demonstrated successful early and midterm patient-reported outcomes. The purpose of this study was to evaluate the posterior and anterior extent and size of labral tears in patients with FAIS undergoing arthroscopic labral repair, and to evaluate the number of suture anchors required to repair these tears. The design of this study was retrospective case series (Level 4). A single surgeon's operative database was retrospectively reviewed to identify patients undergoing primary arthroscopic hip labral repair between November 2014 and September 2019. Patient-specific factors and radiographic measurements were recorded. Arthroscopic findings including labral tear posterior and anterior extents, and the number of suture anchors utilized for the repair were recorded. Linear regression was performed to identify factors associated with labral tear size. The number of suture anchors used relative to labral tear size was calculated. Three-hundred and thirteen patients were included in the study. The mean posterior and anterior extent for labral tears were 11:22 ± 52 and 2:20 ± 34 minutes, respectively. Mean tear size was 2 hours, 58 minutes ± 45 minutes. The mean number of suture anchors utilized for labral repair was 3.1 ± 0.7. The mean number of anchors per hour of labral tear was 1.1 ± 0.3. Increased age, lateral center edge angle, and α angle were associated with larger labral tears. Our study found that acetabular labral tears associated with FAIS are, on average, 3 hours in size and centered in the anterosuperior quadrant of the acetabulum. Arthroscopic labral repair required 1.1 anchors per hour of tear size, resulting in a mean of 3.1 anchors per repair.
