Young females are at a 2 to 6 times increased risk of non-contact ACL injury compared to males.
This happens because after puberty, as their body size increases, girls do not usually develop more muscle power. And female athletes between 15 and 20 years old, account for the largest number of ACL injuries.
At high school level, girls soccer has the most ACL injuries, followed by boys football, girls basketball, girls gymnastics, and boys and girls lacrosse. Among high school and college athletes, females have two to six times higher ACL injury rates than males in similar sports. Compared with boys, girls are more likely to have surgery and less likely to return to sports after an ACL injury.
