From the Othopedics Today article:
Researchers evaluated 70 professional hockey players with an average age of 27 years who underwent hip arthroscopy to treat femoroacetabular impingement (FAI) between 2005 and 2010. Player data, such as position played, draft position, perioperative age and length of professional career, and surgical details were analyzed. The average length of a professional career was determined by the researchers to be 13 years as of the 2015 to 2016 hockey season.
Overall, 40 patients (57%) played professionally for a minimum of 5 years and played for an average of 6.9 years following hip arthroscopy. Patients who played a minimum of 5 years professionally were significantly younger (average age of 25 years) than those who did not (average age of 30 years). Career length and postoperative years played were linked with age at the time of operation, according to results of a multiple regression analysis.
