Osgood-Schlatter disease is a chronic strain of the ligament that attaches the patella (knee cap) to the lower leg(tibia). The point on the tibia where the ligament attaches becomes inflamed, tender and at times swollen. Parents may become concerned about the rather large tender bump that becomes visible on the leg below the kneecap. More common in boys, the pain is generally associated with activity, especially those activities that involve frequent bending of the knee.

Treatment involves limitation of painful activities. Your son can continue to play soccer if the pain is not too great. Once children begin to limp because of discomfort, they must cease the activity. Discomfort after activities should be treated with ice and anti-inflammatory medications like ibuprofen. Because there is no weakness, bracing of the knee is of no benefit. The pain usually resolves once full growth is attained and the growth plates in the leg close.

While Osgood-Schlatter is more common in boys, girls may develop similar types of knee pain that have different origins. The wider female pelvis puts different stresses on the knee and muscle imbalances develop that lead to knee pain. The knee cap may be pulled over to the side of the knee causing irritation of the cartilagee and pain, in a condition called chondromalacia patella.

This condition is also worsened by activites that involve knee bending. However, since this pain is due to a muscle imbalance, stretching and strength training can help overcome the difficulties and activity rarely need be limited.

If your child develops knee pain that doesn¹t resolve in a few days, be sure to have them examined by their pediatrician. Rarely knee pain can be a sign of more serious illness.
