What Is Osgood Schlatter Disease?
3. Causes
The tibial tubercle is a bony prominence at the shinbone where it forms the knee joint. The patellar tendon attaches the quadriceps muscle in the thigh to the shinbone at the tibial tubercle. Frequent motion of the quadriceps puts pressure on the tibial tubercle, which strains the growth plate.
The growth plate is already under stress because of the rapid changes that take place during an adolescent’s growth spurt. Because the cartilage of the growth plate is more susceptible to injury than bone, the combined stress of repetitive physical activity and strain caused by a growth spurt can cause symptoms of inflammation and pain at the tibial tubercle and patellar tendon.
