Inflammation of the bone below the knee caused by stress to the patellar tendon.

Osgoode-Schlatter disease refers to the inflammation of the growth plate at the tibial tuberosity (the bump of bone just below the kneecap). It occurs most commonly in active youth aged 11-15 and often coincides with a growth spurt. Pain, swelling and tenderness develop at the front of the knee, below the kneecap (patella). The symptoms are aggravated by running and jumping and the increased stress on the patellar tendon that attaches the quadriceps muscle at the front of the thigh to the tuberosity can lead to excessive bone growth and a lump may develop.

The application of the red and infrared laser light can relieve the pain of Osgood-Schlatter's Disease by increasing the production of serotonin and endorphins, the body's natural pain regulating substances. In addition, the laser increases circulation, lymphatic drainage and cellular activity to relieve the associated inflammation and facilitate the repair and result in stronger healed tissue structures.
