What is Osgood-Schlatter’s Disease?
Osgood-Schlatter’s Disease is a temporary condition involving pain and swelling in the small bump of the tibia (shin) bone just below the knee. This small bump, called the tibial tubercle, is where the patellar tendon attaches the shinbone (tibia) to the kneecap (patella). The major thigh muscle (quadriceps muscle) also attaches to the kneecap and shinbone through the patellar tendon. Thus, the patellar tendon acts as a sort of pulley system over the knee with the flexion and extension of the leg while walking, running, and jumping.
When there is too much stress on the patellar tendon, it pulls on the bone and growth plate at the tibial tubercle, causing the pain and swelling that come with Osgood Schlatter’s disease.
