Osteochondroma of tibial tuberosity in a young soccer player mimicking an Osgood-Schlatter disease: A case report and literature review.

We report a case of a 9-year-old male with anterior knee pain and swelling associated with physical activity. The orthopedic surgeon suspected Osgood-Schlatter's disease. X-ray and MRI showed an osteochondroma of the tibial tuberosity. The patellar tendon partially inserted on the osteochondroma and the tibial tubercle, causing pain associated with physical activity. We chose a conservative management with temporary rest, local application of ice and NSAIDs. After a few weeks, the boy returned to regular training without pain and our final recommendation was only radiological monitoring of the lesion over the time.
