The Largest Osteochondral Fracture of Patella, Case Report

Fractures of the patella, generally occuring by direct trauma, constitute 1% of all fractures. The most comprehensive classification of the patella fractures is the Orthopaedic Trauma Association (OTA) classification. This is a report of a 15-year-old male patient examined after falling down and sufferred from a patella fracture. The fracture could not be classified by the current classifications. At the operation, the extensor mechanism was normal and the medial joint surface of the patella was displaced superiorly. The fragment was considered as a very big osteochondral fragment and two headless full-threaded compression screws were used for fixation.
