Information On Osgood-Schlatter Disease

Information On Osgood-Schlatter Disease
According to the American Academy of Orthopaedic Surgeons, more than 4.1 million people
seek medical care each year for a knee problem.

Some knee problems result from wear of parts of the knee, such as occurs in
osteoarthritis. Other problems result from injury, such as a blow to the knee or sudden

movements that strain the knee beyond its normal range of movement.

Osgood-Schlatter disease (also osteochondrosis or tibial tuberosity) is caused by

repetitive stress or tension on a part of the growth area of the upper tibia (the

apophysis). It is characterized by inflammation of the patellar tendon and surrounding

soft tissues at the point where the tendon attaches to the tibia. The disease may also be

associated with an avulsion injury, in which the tendon is stretched so much that it tears

away from the tibia and takes a fragment of bone with it. The disease most commonly

affects active young people, particularly boys between the ages of 10 and 15, who play

games or sports that include frequent running and jumping.

People with this disease experience pain just below the knee joint that usually worsens

with activity and is relieved by rest. A bony bump that is particularly painful when

pressed may appear on the upper edge of the tibia (below the knee cap). Usually, motion of

the knee is not affected. Pain may last a few months and may recur until a child's growth

is completed.

Osgood Schlatter disease is most often diagnosed by the symptoms. An x ray may be

normal, or show an avulsion injury, or, more typically, show that the apophysis is in

fragments.

Usually, the disease disappears without treatment. Applying ice to the knee when pain

first begins helps relieve inflammation and is sometimes used along with stretching and

strengthening exercises. The doctor may advise the patient to limit participation in

vigorous sports. Children who wish to continue participating in

moderate or less stressful sports may need to wear knee pads for protection and apply ice

to the knee after activity. If a great deal of pain is felt during sports activities,

participation may be limited until any remaining discomfort is tolerable.
