Today, 30 million U.S. children are getting in the game. Unfortunately, every year a growing number - 3.5 million children under the age of 14 - need medical care for sports injuries.

The popularity of high school sports is at an all-time high, with more than 7.3 million student athletes. This group accounts for 2 million injuries, 500,000 doctor visits and 30,000 hospitalizations every year, according to the Centers of Disease Control and Prevention.
