A recent study looked at overuse injuries in collegiate and high school sports. These injuries were primarily reported in noncontact running
In each population, the rate of overuse injury was higher among females compared with male athletes in sex-comparable sports.
Approximately 70% of overuse injuries were reported to the lower extremity in both college and HS athletes. Specifically, 20.0% of college and 16.0% of HS overuse injuries reported were to the knee, and 18.6% of college and 22.5% of HS overuse injuries were to the lower leg. Other commonly injured body sites were the shoulder and lower back.
