Osgood-Schlatter Disease

Osgood-Schlatter disease is an avulsive injury of the patellar tendon at its distal attachment to the tibial tuberosity which results in a painful tibial tuberosity. The condition is most prevalent in pre-adolescent boys (5:1 boys > girls).

The radiologic findings of Osgood -Schlatter disease include:

  • soft tissue swelling about the patellar tendon
  • thickened patellar tendon
  • loss of infrapatellar fat pad
  • irregularity of the tibial tuberosity
