Abstract Purpose The purpose of the current study was to establish a risk stratification for hip injury by presenting the classification of sports among adolescent athletes undergoing hip arthroscopy. Methods A multicentre registry was queried to examine the incidence of adolescent athletes undergoing hip arthroscopy. Patients were identified and grouped according to their sport-specific risk classification (level I–III). Chi-square analysis was performed to determine the relationship of classification of sport and gender in adolescent athletes to hip arthroscopy. A second chi-square analysis was performed to determine the relationship of classification of sport and number of sports the adolescent athlete was participating in prior to arthroscopic hip surgery. Results A total of 297 adolescent athletes were included in the study with 129 (43.4%) participating in level I sports compared with 84 (28.3%) in level II and 84(28.3%) in level III sports. Chi-square testing demonstrated a significant effect on gender and sport classification, X2 (2, N = 297) = 31.18, p < 0.01. There was a greater percentage of athletes participating in a single sport (65.3%) compared with multiple sports (34.6%), but was not statistically significant, X2 (1, N = 297) = 1.88, p = 0.17. Conclusion The current study was successful in stratifying a large, multicentre cohort of adolescent athletes requiring hip arthroscopy based on classification levels of sport. There were more male athletes participating in level I sports, while more female athletes participated in level II and level III sports. Keywords FAI . Dysplasia . Chondrolabral pathologies .

Introduction Arthroscopic hip surgery is a minimally invasive procedure commonly utilized for the treatment of intra-articular pathology including femoroacetabular impingement and chondrolabral

lesions [1, 2]. Hip arthroscopy techniques are employed to address structural abnormalities, relieve pain, and improve their abilities during common daily activities [3]. For many patients, this includes participation in sports-related activities. While arthroscopic procedures are most commonly performed in the

Institutional Review Board approval for pre-hoc collection and storage of agreed upon de-identified clinical data points was granted at each contributing center. * Ryan P. McGovern [email protected] 1
