Cheerleading injuries less common, more severe than other sports

When Tia Wilson was a senior in high school, she dislocated her kneecap during a tryout for a summer cheerleading camp.

"I was doing a no-handed cartwheel, called an aerial, and I must have landed funny," she told CBS News.

A gymnast since the age of two and a cheerleader since middle school, the injury had severe consequences for Wilson. Nerve complications associated with the injury kept her out of school for eight weeks and off cheerleading for several months.

Wilson's story may sound familiar to thousands of cheerleaders -- and their parents -- across the country.
