Osgood-Schlatter disease is inflammation of the bone and surrounding soft tissue just below the knee. It occurs at the point where the shinbone attaches to the tendon of the kneecap.
Osgood-Schlatter disease is caused by repeated tension or stress on the upper part of the shinbone during its growth spurts.
Factors that may increase your risk of getting this condition include:
- Sex: males are at greater risk than females
- Age: 10 to 18 years old
- Rapid growth spurts
- Activities that stress the patellar tendon, such as jogging, jumping, and sudden turning
- Being overweight
- Pain, swelling, and/or tenderness just below the knee that usually worsens during physical activity
- A swollen, painful bump just below the knee
The doctor will ask about your symptoms, medical history, and physical activity. An examination of your knee will be done. Diagnosis is based on the symptoms. In some cases, you may have an x-ray or an ultrasound of the knee.
Osgood-Schlatter disease may go away when the bones and tendons have finished growing. The bump may be permanent.
Treatment may include:
- Avoid exercise that stresses the patellar tendon until the swelling and pain go away. This may be as short as 1 to 2 weeks, or as long as three months or more.
- Talk to your doctor about using a strap to stabilize the area during sports.
- Use a brace or elastic bandage to support the area as it heals.
- You may be referred to a physical therapist to strengthen the affected muscles.
Pain and swelling may be relieved with:
- Ice compresses during a flare-up or after exercise
- An over-the-counter pain reliever, such as ibuprofen, naproxen, or acetaminophen
- A local injection of cortisone in severe cases
Note : Aspirin is not recommended for children or teens with a current or recent viral infection. This is because of the risk of Reye's syndrome . Ask your doctor which other medicines are safe for your child.
If the patellar tendon has pulled away from the shinbone, surgery may be needed to repair the tendon and remove fragments of bone. In most cases, surgery is not needed.
To prevent the occurrence or recurrence of Osgood-Schlatter disease:
- Encourage overweight children to lose weight.
- Encourage children to exercise regularly but moderately, and to avoid weight-bearing activities that put excessive stress on the patellar tendon. These include jogging, jumping, and sudden turning.
- Ask your child's doctor for stretching and strengthening exercises for the shinbone/patellar tendon.
