You don't even have to go pro. My younger sis has had hundreds of thousands of dollars worth of medical procedures from a few years of high-school running. Turns out even teenagers can have more motivation than springiness.
You're right, this is pretty atypical for runners in general, but unfortunately not for my high school team. Last I'd heard about 50% had been through at least one round of surgery in college, though my sister's definitely one of the worst for wear.
