Avulsion Fracture of the Posterior Cruciate Ligament from Femoral Insertion Occurred in a Patient with Residual Poliomyelitis: A Case Report

ABSTRACT

Avulsion fracture of the posterior cruciate ligament from its femoral insertion is quite rare, particularly in adults, and the treatment guidelines have not been established. A 68-year-old female patient with residual poliomyelitis presented with an avulsion fracture of the femoral insertion of the posterior cruciate ligament after a falling accident and was treated with arthroscopic headless compression screw fixation and pull-out suture of the avulsed ligament. We report this case with a relevant discussion of this type of injury.
