Abstract
Background: The utilization of hip arthroscopy continues to increase in the United States. The purpose of this study was to examine trends in hip arthroscopy procedures and outcomes. Methods: We performed a retrospective cohort study using Optum Labs Data Warehouse administrative claims data. The cohort comprised 10,042 privately insured enrollees aged 18-64 years who underwent a hip arthroscopy procedure between 2005 and 2013. Utilization trends were examined using age-specific, sex-specific, and calendar-year-specific hip arthroscopy rates. Outcomes were examined using the survival analysis methods and included subsequent hip arthroscopy and total hip arthroplasty (THA). Results: Hip arthroscopy rates increased significantly over time from 3.6 per 100,000 in 2005 to 16.7 per 100,000 in 2013. The overall 2-year cumulative incidence of subsequent hip arthroscopy and THA was 11% and 10%, respectively. In the subset of patients in whom laterality of the subsequent procedure could be determined, about half of the subsequent hip arthroscopy procedures (46%) and almost all of the THA procedures (94%) were on the same side. Decreasing age was significantly associated with the risk of subsequent arthroscopy (P < .01), whereas increasing age was significantly associated with the subsequent risk of THA (P < .01). The 5-year cumulative incidence of THA reached as high as 35% among individuals aged 55-64 years. Conclusion: The utilization of hip arthroscopy procedures increased dramatically over the last decade in the 18-64-year-old privately insured population, with the largest increase in younger age-groups. Future studies are warranted to understand the determinants of the large increase in utilization of hip arthroscopy and outcomes.
