Osgood-Schlatter disease or syndrome (also known as tibial tubercle apophyseal traction injury) is an inflammation of the growth plate at the tibial tuberosity, and is one of a group of conditions collectively called osteochondroses. The condition is named after the American surgeon Robert Bayley Osgood (1873–1956) and the Swiss surgeon Carl Schlatter (1864–1934), who independently described the disease in 1903.[1][2][3]
The condition occurs in active boys and girls aged 11-15[4], coinciding with periods of growth spurts. It occurs more frequently in boys than in girls, with reports of a male-to-female ratio ranging from 3:1 to as high as 7:1. It has been suggested the difference is related to a greater participation by boys in sports and risk activities than by girls.
The condition is usually self-limiting and is caused by stress on the patellar tendon that attaches the quadriceps muscle at the front of the thigh to the tibial tuberosity. Following an adolescent growth spurt, repeated stress from contraction of the quadriceps is transmitted through the patellar tendon to the immature tibial tuberosity. This can cause multiple subacute avulsion fractures along with inflammation of the tendon, leading to excess bone growth in the tuberosity and producing a visible lump.
The syndrome may develop without trauma or other apparent cause. But some studies report up to 50% of patients give a history of precipitating trauma.
In a retrospective study of adolescents, young athletes actively participating in sports showed a frequency of 21% reporting the syndrome compared with only 4.5% of age-matched nonathletic controls.[5]
Sinding–Larsen–Johansson Syndrome is an analogous condition involving the patellar tendon and the lower margin of the patella bone, instead of the upper margin of the tibia.
– Knee pain is usually the presenting symptom that occurs during activities such as running, jumping, squatting, and ascending or descending stairs. The pain can be reproduced by extending the knee against resistance, stressing the quadriceps, or squattin
Diagnosis is made clinically,[7] and treatment is conservative with rest and simple pain reduction measures of ice packs and if required paracetamol (acetaminophen) or ibuprofen. The condition usually resolves in a few months, with a study of young athletes revealing a requirement of complete training cessation for 3 months (on average) and gradual resumption of full training by 7 months.[5]
