Cevallos N, Soriano KKJ, Flores SE, et al. - This study was intended to present contemporary trends in hip arthroscopy case volume in the United States using a large cross-sectional cohort with accurate laterality tracking for assessment of revision surgery and rates of conversion to total hip arthroplasty (THA). Researchers used the Mariner PearlDiver dataset to query patients who had undergone hip arthroscopy from 2010 to 2017 using CPT codes. They queried the Emergency department and hospital admission within 30-days after surgery. Hip arthroscopy case volume increased two-fold from 2010 to 2014 but remained relatively unchanged from 2014 to 2017 out of the 53,103 patients undergoing hip arthroscopy procedures. It has been considered that the rise in hip arthroscopy procedures may be starting to plateau in the United States. Results demonstrate that there is a higher than previously reported rate of revision hip arthroscopy in patients under age 30 and conversion to THA in patients over age 50.
