Osgood-Schlatter disease is an inflammatory injury of the growth plate on the tibia (shin bone) just below the level of the knee at the tibial tubercle  This disease may also be referred to as osteochondrosis or apophysitis of the tibial tubercle  The tibial tubercle is the bony attachment for the quadriceps (front thigh muscle). Contraction of the quadriceps results primarily in straightening of the leg at the level of the knee  A growth plate is an area of developing tissue near the ends of long bones or areas of muscle attachment. The growth plates in children allow the bones to expand in length, thus allowing a child to reach their full height by the age of 16 to 19  Compared to the surrounding bone and muscles, the growth plate serves as a weak point. Thus repetitive pulling on a growth plate, especially from a large, powerful muscle like the quadriceps, can result in injury to the growth plate and subsequent pain  Osgood-Schlatter Disease is usually a self-limited disease – upon reaching skeletal maturity, the growth plate seals and thus can no longer cause pain  This condition is very similar in presentation and treatment to Sinding-Larsen- Johansson Syndrome, which is a traction apophysitis of the inferior pole of the patella
