Trends in Hip Arthroscopic Labral Repair: An American Board of Orthopaedic Surgery Database Study

The purpose of this study is to evaluate the trends in labral repair in American Board of Orthopaedic Surgery Part II candidates performing hip arthroscopy.

Candidates who performed arthroscopic hip surgery between 2011 and 2015 during their American Board of Orthopaedic Surgery Part II board collection period were identified using Current Procedural Terminology codes (29860, 29861, 29862, 29863, 29914, 29915, 29916). The proportion of hip arthroscopy cases including labral repair (Current Procedural Terminology code 29916) were calculated for each year and analyzed by fellowship training experience. Trends in labral repair utilization were calculated using univariate and regression analyses, with significance set at P < .05.

During the study period, 1,606 hip labral repair cases were performed, with a 35% increase in utilization between 2011 and 2015. Overall, labral repair was performed in 64.8% (1,606/2,480) of hip arthroscopy cases, with a significant increase between 2011 and 2015 (47.4% vs 79.2%; P < .001). Of the hip arthroscopy cases including labral repair, 80.4% (1,291/1,606) were performed by candidates with sports medicine fellowship training. The proportion of hip arthroscopy cases including labral repair was highest for surgeons with sports medicine fellowship training compared with those without sports medicine fellowship training (66.1% vs 59.8%; P = .007). Candidates with sports medicine training performing at least 1 labral repair each year increased from 68% to 89% over the study period (P = .0007). The average number of labral repairs per candidate increased significantly over the duration of the study period (P = .0072).

Labral repair utilization during hip arthroscopy procedures nearly doubled from 2011 to 2015 for American Board of Orthopaedic Surgery Part II candidates, reflecting a significant change in practice. Current data suggest that nearly 80% of hip arthroscopy procedures include labral repair. These trends may reflect the current practice patterns at academic institutions with sports medicine fellowships.
