Fracture of an unossified tibial tubercle

A rare fracture of an unossified tibial tubercle in a 12-year-old boy is presented. Resisted active extension was the mechanism of injury. Clinical examination demonstrating tibial tubercle pain and crepitation and weakness of knee extension and radiographs showing a unilateral high-riding patella led to the suspicion of a fracture through the unossified tubercle. Operative treatment with appropriate fixation was performed, and an excellent result was obtained.
