An unusual radiographic presentation of posterior cruciate ligament avulsion fracture.
A case of traumatic posterior cruciate ligament (PCL) avulsion fracture presenting with unusual radiographic findings is described. CT scan of the right knee showed features suggestive of combined ACL and PCL avulsion fractures. Arthroscopic findings showed that the injury was in fact a PCL avulsion fracture that was displaced anteriorly so as to mimic an ACL avulsion fracture on CT scan.
