Femoroacetabular impingement (FAI) syndrome is commonly identified in high-performance athletes. A study of 172 professional athletes playing for the National Football League (NFL), Major League Baseball (MLB), National Basketball Association (NBA), and National Hockey League (NHL) showed that after arthroscopic treatment for FAI, the return-to-sport rate was high across the board. Only NHL athletes had significantly shorter careers and played fewer games per season than their matched control players. NHL athletes demonstrated worse postoperative performance compared with preoperative performance. Athletes in all other sports showed a career-related decline similar to that of matched control players.
