The main risk factors for Osgood-Schlatter disease are:

  • Age. Osgood-Schlatter disease occurs during puberty's growth spurts. Age ranges differ by sex because girls experience puberty earlier than do boys. Osgood-Schlatter disease typically occurs in boys ages 13 to 14 and girls ages 11 to 12.
  • Sex. Osgood-Schlatter disease is more common in boys, but the gender gap is narrowing as more girls become involved with sports.
  • Sports. The condition happens most often with sports that involve a lot of running, jumping and swift changes in direction.
