Osgood-Schlatter disease


Osgood-Schlatter disease, also called tibial tuberosity apophysitis, is a disorder that causes temporary pain, tenderness, and swelling of the knee. In most cases, pain and swelling occurs at the lower front of the knee under the kneecap, called the tibial tuberosity. This is where a large tendon, called the patellar tendon, attaches to the shinbone (called the tibia). One or both knees may be affected.
Many experts believe that overuse of the knee may cause the disorder. Physical activities that involve running or jumping, (e.g. soccer, gymnastics, or basketball) may lead to Osgood-Schlater disease because they put a lot of stress on the knees.
Osgood-Schlatter disease only occurs in adolescents because their bones are still growing. The frequency of Osgood-Schlatter disease in the United States is unknown, but it is considered uncommon. In general, boys ages 13-14 and girls ages 11-12 are most likely to be affected. It is more common in boys than girls. It is also more common among athletes than non-athletes.
Although Osgood-Schlatter may be painful, it is temporary and only lasts about four to six weeks. Until the condition goes away on its own, people may be encouraged to limit exercises that worsen symptoms. Pain relievers and anti-inflammatories may also help reduce symptoms. Symptoms may also come back from time to time until the person has stopped growing.
