BACKGROUND
Avulsion injury to the tibial attachment of posterior cruciate ligament (PCL) is frequently occur. The purpose of this report is to highlight an unusual variation of PCL avulsion injury.
CASE PRESENTATION
A 24-year-old female was suffered a motorcycle accident 1 day before admission. The patient complained of severe right knee pain. Plain radiograph and CT-scan revealed an anteriorly displaced tibial attachment PCL avulsion fracture. Open surgical fixation was done to the patient. A satisfactory outcome was observed until the final 1-year follow-up.
CONCLUSIONS
The bony fragment of the tibial attachment of posterior cruciate ligament avulsion injury can be displaced to the anterior compartment of the knee. Concomitant injury to other knee structures should be suspected when finding this case. Special consideration is also needed during the management of this unusual case.
