Once a diagnosis has been made, treatment is aimed at reducing the pain and swelling. This may include the use of nonsteroidal anti-inflammatory drugs and wrapping the knee until the child can enjoy activity without discomfort or significant pain afterwards.
Symptoms that worsen with activity may require rest for several months, followed by a conditioning program. In some patients, Osgood-Schlatter symptoms may last for 2 to 3 years. However, most symptoms will completely disappear with completion of the adolescent growth spurt, around age 14 for girls and age 16 for boys.
