I am familiar with Osgood-Schlatter Disease...
It is not uncommon and no long term effects...
Children [usually] with Osgood-Schlatter disease have a tender, swollen bump just under their knee cap on the tibial tuberosity. Although usually just on one knee, both knees can also be affected.
Unlike other problems that cause knee pain, children with Osgood-Schlatter disease usually just have pain during certain activities, such as running, kneeling, jumping, squatting, and climbing stairs. Prolonged sitting sometimes also causes pain, although affected children can usually walk normally without pain or a limp.
What You Need To Know
- Osgood-Schlatter disease usually begins during a period of active growth (growth spurt) in children between the ages of 10 and 15 years who are active in sports.
- Although once thought to affect mainly boys, as more girls participate in sports, Osgood-Schlatter disease is being increasingly seen in girls too. Girls do usually seem to be younger when their symptoms start, at 10-11 years, versus 13-14 years for boys. This is likely because girls usually go through their growth spurt before boys.
- Osgood-Schlatter disease is thought to be caused by chronic microtrauma and it is considered an overuse disorder.
- Symptoms usually last about 12-18 months, with a nontender bump lingering in many children.
- Quadriceps and hamstring flexibility exercises might help prevent Osgood-Schlatter disease from developing.
- Proper early diagnosis can help prevent unnecessary testing and treatments.
- Sinding-Larsen-Johansson disease or jumper's knee is a similar condition, but the pain is usually over the lower part of the knee cap and not below the knee cap as it is in Osgood-Schlatter disease.http://pediatrics.about.com/cs/orthopedics/a/osgoodschlatter.htm
