Osgood-Schlatter disease happens where there is a painful lump located below the kneecap in children and adolescents who are going through growth spurts during puberty. However, this can also happen at an older age.

Injury Overview


Osgood-Schlatter disease is caused by small injuries to the knee area from overuse that happens before the knee is actually finished growing. If the quadricep muscle gets used a lot in sports at the same time the child is going through a growth spurt, this can cause it to become swollen and cause pain. Any sort of repeater stress can make the tendon pull away from the shinbone which results in pain and swelling associated with the disease. The body may try to close that gap where there is bone growth, which can easily turn into a bony lump at that spot.


Osgood-Schlatter does not usually need surgery to get better. Symptoms typically disappear after your child’s bones stop growing. Until that happens, your doctor Is likely to recommend pain relievers and physical therapy. This will teach your child exercises they can do to help in reducing the tension where the kneecap tendon is attached to the shinbone. Children who have this should cease all sports for two or more months to allow the disease to get better. Adolescents can play if they are not in too much pain. In the most rare of cases, surgery may be needed to fix the issue.


Prevention may be hard with this disorder simply because the small injuries that cause it often go unnoticed. As always it is a good idea to wear proper footwear during any activity and use good form with any exercise you are performing. Usually, Osgood-Schlatter goes away on its own with rest and time. However, if your child tries to ignore and play through the pain, the disease is much more likely to get worse and harder to treat.
