Osgood Schlatter disease, also referred to as osteochondrosis and apophysitis of the tibial tubercle, is a condition that causes pain directly over the attachment site of the kneecap tendon (patellar tendon) to the lower leg bone (tibia.) The bump on the top of the tibia (called the tibial tubercle) is a normal bump on the bone of the lower leg where the patellar tendon attaches. The strong thigh muscles (quadriceps) attach to the kneecap and thus to the lower leg through the patellar tendon, and act to straighten out the leg for everyday activity such as walking and standing as well as sports activities such as running, jumping, cycling and climbing. With Osgood Schlatter disease, the quadriceps muscles are pulling hard enough to cause a repetitive injury to the growth plate of the tibial tubercle. We see this condition mainly during childhood and it will often resolve completely after children have reached their skeletal maturity. During the phase of pain, there are many conservative measures that can be used to alleviate the discomfort while the body is growing. Dr Vizzi treats pediatric patients for a number of orthopedic conditions including Osgood Schlatter disease and he can help you improve the symptoms of this often painful condition.
