Transverse Avulsion Patellar Fracture

Transverse Avulsion Patellar Fracture

Caused by indirect force generated by the quadriceps tendon.
Transverse fractures of the patella are much more common than longitudinal or comminuted fractures.
As with all patellar fractures, it is important to differentiate between fracture and bipartite or multipartite patella.

In the image shown below, the distal portion of the patella was avulsed.
