MCL tears, while common in adults, are less common for children. But teenage athletes are more likely to injure their MCL than other teenagers. This is especially true if they play sports that put them at risk of colliding with other players from the side, such as football and ice hockey.
Older children are more likely to injure their MCL than children who are younger than age 12. Younger children more often break the bone where the ligament attaches.
