Introduction: The purpose of this study was to evaluate the changing incidence of hip arthroscopy procedures among newly trained surgeons in the United States, the indications for hip arthroscopy, and the reported rate of post-operative complications.
Methods: The ABOS database was used to evaluate the annual incidence of hip arthroscopy procedures between 2006-2010. Procedures were categorized by indication and type of procedure. The rate of surgical complications was calculated and compared between the published literature and hip arthroscopy procedures performed for femoroacetabular impingement (FAI)/osteoarthritis (OA) and for labral tears among the newly trained surgeon cohort taking the ABOS Part II Board exam.
Results: The overall incidence of hip arthroscopy procedures performed by ABOS Part II examinees increased by over 600% during the 5-year period under study from approximately 83 in 2006 to 636 in 2010. The incidence of hip arthroscopy for FAI/OA increased steadily over the time period under study, while the incidence of hip arthroscopy for labral tears was variable over time. The rate of surgical complications was 5.9% for hip arthroscopy procedures for a diagnosis of FAI/OA vs. 4.4% for a diagnosis of labral tear (P=0.36).
Conclusions: The incidence of hip arthroscopy has increased dramatically over the past 5 years, particularly for the indication of FAI/OA. Reported surgical complication rates are relatively low, but appear higher than those rates reported in previously published series. Appropriate indications for hip arthroscopy remain unclear.
