Tibial Tubercle Avulsion

In brief: Tibial tubercle avulsion is an uncommon injury that has a peak incidence in early adolescence near the time of physeal closure. Because growth arrest and deformation can follow this injury, immediate diagnosis and treatment are essential. In this case a 14-year-old boy sustained a type 2 tibial tubercle avulsion while playing basketball and could not walk without assistance. Closed reduction was not possible because of soft-tissue interposition.
