Introduction: Anterior tibial tubercle fractures are relatively infrequent and occur mainly in young athletes 14 to 17 years old. Most fractures result from jumping during sports activities.
Methods: We describe two cases of anterior tibial tubercle fractures. The latter were Ogden IIIA and IIIB. In both cases treatment consisted of open reduction and internal fixation with cannulated screws.
Discussion: The mechanism of injury in the first case is more common than the one in the second case. The first case occurred after jumping to receive a pass during a basketball game. The second one occurred while playing soccer. The patient was kicked on the quadriceps musculature. Both cases involved functional disability.
Conclusion: Biomechanically, the mechanism of injury in the second case increased the tension on the extensor apparatus. We performed synthesis with cannulated screws and obtained good results without complications.
