Abstract
Tibial avulsion fracture of the posterior cruciate ligament (PCL) is a rare condition, and surgical fixation of the fragment is a controversial treatment. In the present study we report three cases (two men and a woman) of PCL avulsion that were treated with screw fixation through the posterior approach. Injuries resulted from a fall in one man and the woman, in the remaining patient it was the consequence of a car accident. The X-rays and MRIs revealed that the PCL was detached from the tibial attachment with relatively big fragments, for that reason the PCL was relaxed. The fragment was reduced and fixed at the anatomical position with cannulated cortical screws by using the direct posterior approach.
Full range of motion and attained good stability of the knee without pain was achieved within six postoperative months in all patients.
In conclusion, the screw fixation of the fragment through the posterior approach is a safe and effective treatment for tibial avulsion fracture of the PCL.
