Background: The effect of hip arthroscopy on athletic performance compared with preinjury levels for professional athletes in different sports remains unknown. In addition, while return rates have been reported for professional baseball, football, and hockey players, return rates have not been reported for professional basketball players.
Hypothesis: Professional athletes in 4 major North American sports would be able to return to their sport and preoperative level of performance at a high rate after arthroscopic hip surgery.
Study Design: Descriptive epidemiology study.
Methods: Major League Baseball (MLB), National Basketball Association (NBA), National Football League (NFL), and National Hockey League (NHL) athletes who underwent hip arthroscopy were identified through a previously reported protocol based on public sources. Successful return to play (RTP) was defined as returning for at least 1 professional regular season game after surgery. Performance scores were calculated by use of previously established scoring systems. Each player served as his own control, with the season prior to surgery defined as baseline. To make comparisons across sports, the authors adjusted for expected season and career length differences between sports and calculated percentage changes in performance.
Results: The authors identified 227 procedures performed on 180 professional athletes between 1999 and 2016. Successful RTP was achieved in 84.6% (192/227) of the procedures. Compared with all other athletes, NBA athletes returned at a similar rate (85.7%, P ≥ .999). NFL offensive linemen returned at a significantly lower rate than all other athletes (61.1%, P = .010). NHL athletes returned at a significantly higher rate than all other athletes (91.8%, P = .048) and demonstrated significantly decreased performance during postoperative season 1 compared with baseline (–35.1%, P = .002). Lead leg surgery for MLB athletes (batting stance for hitters, pitching stance for pitchers) resulted in a 12.7% reduction in hitter performance score (P = .041), a 1.3% reduction in pitcher fastball velocity (P = .004), and a 60.7% reduction in pitch count (P = .007) one season after surgery compared with baseline. Players in nearly every sport demonstrated significant reductions in game participation after surgery.
Conclusion: This study supports the hypothesis that hip arthroscopy in professional athletes is associated with excellent rates of return at the professional level. However, postoperative performance outcomes varied based on sport and position.
