Many times the condition occurs right after a growth spurt. Pain is reproduced when firing the quadriceps or increasing stress on the tibial tuberosity. Over the long haul, Osgood-Schlatter's can alter the position of the knee cap and predispose a person to chondromalacia patella or patella-femoral syndrome. Proper treatment from the beginning is important.
When diagnosing and assessing Osgood-Schlatter's disease, special attention must be placed on global assessment of the whole kinetic chain. Many times imbalances in the pelvis can lead to increased tension on the quadriceps muscle on one side. The hypertonic quadriceps leads to inflammation and pain at the tibial tuberosity. X-ray or MRI testing can be performed to determine the full extent of the injury.
