Comminuted fracture of the tibial tuberosity with two dominant fragments and multiple other smaller fragments. No definite extension into the proximal tibial physis. The patella is high riding with an increased Insall-Salvati ratio of >1.2.
Case Discussion
Tibial tuberosity avulsion fractures are relatively common fractures, typically occurring in sports-playing adolescent males. It is important to assess for associated patella alta deformity, which this case nicely demonstrates.
