Show Content What is Osgood-Schlatter disease?Osgood-Schlatter disease is a condition that can cause pain in the knees of children and adolescents. It is often associated with a growth spurt and usually gets better with simple treatment. The condition most often affects children aged 9-14 years. It is more common in children who are very physically active, particularly when activities involve a lot of running and jumping, such as football, gymnastics, cricket, basketball and ballet. While the affected knee can be painful and may require a temporary slowdown of sporting pursuits, the good news is that children with Osgood-Schlatter disease can generally continue to be active, as the condition will gradually settle with time, when the bones stop growing. CausesThe patellar tendon is important in movement of the knee. The tendon connects the quadriceps muscle in the front of the thigh to the tibia (shinbone) at a point just below the kneecap. This attachment point normally forms a small lump or protuberance that is known as the tibial tuberosity. When the quadriceps muscle contracts, the knee straightens. If the patellar tendon becomes too tight, it can pull on the tibial tuberosity. This can cause:
Risk factorsThe tendon can be more likely to pull on the tibial tuberosity if:
Boys have historically been more likely to experience symptoms; however, this may be because they have tended to be more physically active than girls. Because the growth spurt that coincides with puberty tends to happen a little earlier in girls, they are more likely to have symptoms at a slightly younger age (around 11-12 years of age) compared to boys (around 13-14). Signs and symptomsOsgood-Schlatter disease may affect one knee or both. When both knees are involved, one is often worse than the other. Osgood-Schlatter disease is suspected when pain in the knee tends to:
Other symptoms include:
Methods for diagnosisOsgood-Schlatter disease can usually be diagnosed by a doctor from a physical examination. They will examine the affected knee and look for tenderness and may ask the child to move, squat, or straighten the knee against resistance, to see if this causes pain. X-rays may be recommended, but are often not necessary to diagnose Osgood-Schlatter disease. Other tests may be recommended if the cause of the symptoms is unclear and other conditions need to be ruled out. Types of treatmentIn general, symptoms will disappear once the growth of the bone stops. This can take months to a year or two. To manage the symptoms, the following can be helpful:
Potential complicationsPotential complications of Osgood-Schlatter disease include:
Rarely, symptoms may continue to be troublesome after the bone stops growing. Surgery is not commonly recommended, but may be performed to:
PrognosisFor most children with Osgood-Schlatter, symptoms will settle as their bones stop growing. For a few children, some pain may continue, but the condition rarely requires surgery. PreventionBecause the initial injuries are small, Osgood-Schlatter disease is difficult to prevent. However, following medical advice may help to reduce the risk of the condition becoming worse and doing more damage to the bone. References
