The pain associated with Osgood-Schlatter disease varies from person to person. Some have only mild pain while performing certain activities, especially running and jumping. For others, the pain is nearly constant and debilitating.
Osgood-Schlatter disease usually occurs in just one knee, but sometimes it develops in both knees. The discomfort can last from weeks to months and may recur until your child has stopped growing.
When to see a doctor
Call your child's doctor if knee pain interferes with your child's ability to perform routine daily activities. Seek medical attention if the knee is also swollen and red, or if the knee pain is associated with fever, locking or instability of the knee joint.
