A thick tendon joins the thigh muscle to the kneecap. Another tendon joins the kneecap to the shinbone just below the knee. Osgood-Schlatter disease is an inflammation with pain and swelling at the point where the tendon connects to the shinbone. It happens in young teens during times of rapid bone growth. It is more common in kids who participate in high impact sports such as soccer, gymnastics, basketball, and distance running.
Symptoms may take 6 to 24 months to go away completely. They will usually resolve by the end of the growth spurt. This is about age 14 for girls and age 16 for boys. Even after symptoms go away, a bump may remain on the shinbone. This won’t get in the way of knee function.
Treatment consists of limiting sports activities that make your symptoms worse. You may also use padding for kneeling activities. Anti-inflammatory medicines can help relieve pain and swelling. More severe cases may require crutches for a while.
Apply an ice pack over the injured area for 15 to 20 minutes every 3 to 6 hours. You should do this for the first 24 to 48 hours. You can make an ice pack by filling a plastic bag that seals at the top with ice cubes and then wrapping it with a thin towel. Be careful not to injure your skin with the ice treatments. Ice should never be applied directly to skin. Continue the use of ice packs for relief of pain and swelling as needed.
You may use over-the-counter pain medicine to control pain, unless another medicine was prescribed. Anti-inflammatory pain medicines, such as ibuprofen or naproxen, may be more effective than acetaminophen. If your child has chronic liver or kidney disease or ever had a stomach ulcer or gastrointestinal bleeding, talk with your healthcare provider before using these medicines.
You may use a knee wrap or strap over the insertion of the patellar tendon (the tender point). Also wear a protective knee pad. These measures can relieve stress on the tendon during high-impact sports.
Activities may be continued as long as pain is not severe and doesn't last longer than 24 hours. You may not be able to squat or kneel for long periods of time. Other activities, such as cycling or swimming, may be necessary until symptoms improve. These activities don’t stress the knee as much.
Follow up with your healthcare provider, or as advised.
