Abstract
PURPOSE: To assess the practice trends in hip arthroscopy, including femoroplasty, acetabuloplasty, and labral repair Current Procedure Terminology, 4th edition (CPT-4), codes that have been implemented since many of the previous studies were published, without concerns for Hawthorne or observer effect as can be seen during a board collection window, and in a larger volume of patients with a more comprehensive database than previous published data. METHODS: The MarketScan Commercial Claims and Encounters database was searched using CPT-4 codes to identify patients who underwent any arthroscopic hip procedure from 2008 to 2013. Patients identified were characterized by gender, age group, and year of the initial procedure. Regression analysis was used to evaluate differences in surgical trends between individual patient groups delineated by age and gender. The Cochran-Armitage trend test was used to identify significant differences in surgical trends seen yearly. RESULTS: A total of 62,782 arthroscopic hip procedures in 31,569 surgeries in 27,997 patients were identified and included from 2008 through 2013. The number of surgeries in the database increased every year. After changes to CPT coding in 2011, femoroplasty became the most common procedure in 2012, comprising 28% of all procedures performed in 2013. Patients ages 40 to 49 underwent the most procedures (7,467, 27%). Females were more likely to undergo any arthroscopic procedure during the study period (.068% vs .041%, P < .0001). A total of 2,754 patients (10%) underwent a second surgery during the study period. A total of 1,625 patients (6%) underwent a total hip arthroplasty following an arthroscopic procedure during the study period. CONCLUSIONS: Arthroscopic hip procedures continue to increase, with femoroplasty, labral repair, and acetabuloplasty being the 3 most common procedures performed. Females are more likely to undergo any procedure, and labral repair is now performed more commonly than labral debridement. LEVEL OF EVIDENCE: Level IV, cross-sectional study.
