Arthroscopic repair of a posterior cruciate ligament avulsion.

Abstract

Isolated posterior cruciate ligament injuries are rare and their management is controversial. Bony avulsion fractures have commonly been repaired with open reduction and internal fixation using the posterior approach described by Trickey. However, this approach does not lend itself to detection and repair of associated injuries. We report the case of a posterior cruciate ligament avulsion that was arthroscopically reduced and stabilized with cannulated screws. This technique provided rigid fixation for early rehabilitation and allowed concomitant arthroscopic examination of the knee for any associated injuries.
