This study investigated the epidemiology of injuries in professional soccer players over a 3-year period, using definitions established by the Federation Internationale de Football Association.

The studied identified 5 main results. (1) A total of 211 injuries were recorded over the 3 seasons; 144 were traumatic injuries and 67 were overuse injuries. (2) Injury rates were lower during 2011 than during 2009, especially the rates of overuse injuries. Injury rates during practice were lower in 2011 than in 2010, and overuse injury rates during games were lower in 2010 than in 2009. (3) Lower extremity injuries accounted for 87.7% of the reported injuries; the ankle was the most commonly affected site. (4) Joint and ligament as well as muscle and tendon injuries accounted for 70% of all injuries. (5) During games, injury rates were lower for goalkeepers than for other players.

This study showed that measures should be taken to prevent traumatic injuries during preseason practice and during games. Similarly, preventive measures are needed to reduce overuse injuries during the season.
