Two professional groups, one of surgeons and the other of athletic trainers, are fielding an educational campaign on the prevalence of knee injuries among girls. Tears to the ACL, or the anterior cruciate ligament in the knee, are eight times more likely in girls than in boys, research shows. Doctors hypothesize that physiological differences between girls and boys, such as weaker hamstring muscles that reduce the stability of the knee joint, or estrogen that leads to weaker ligaments, are factors.
The educational campaign comes amid rising questions about the pressures on young athletes. Mark Hyman, author of a book on the topic, says he regrets having supported his son in pitching so long and hard in high-school baseball that he injured his arm, forcing surgery and a permanent setback. And recent research on 5,000 promising football players shows high-school and college injuries haunt pro players for years.
