The numbers of kids showing up in the doctor’s office with overuse injuries, such as tendonitis, is climbing dramatically, according to Boston Children's Hospital. Nationally renowned orthopedic surgeon, Dr. James Andrews, said that he is seeing four times as many overuse injuries in youth sports than five years ago and more kids are having surgery for chronic sports injuries. Experts attribute this increase to the fact that more youth today are specializing in one sport at an early age and training year-round. All these injuries can be linked to overuse – doing too much, too often. (Elizabeth Quinn/About Sports Medicine)
