Background & Objectives: Posterior cruciate ligament is very important in stabilizing knee joint and its rupture and avulsion may result in instability and joint degeneration. The aim of this study was to evaluate the operation outcome of PCL ligament binding site avulsion.

Material & Methods: In present study about 30 patients with avulsion fracture on Tibial PCL binding site were undergone the open surgery and fixation with screw. The patients were followed up for at least 6 months after the operation and were evaluated by the Lysholm Knee Score checklist.

Results: The mean age of patients was 28 years. The common injury mechanism for these patients was motor accident with machine (MCA). On the Lyshom Knee Score, twenty one persons (70%) scored as good (60-90) and 9 (30%) cases were scored as fair (30-59), with a mean score of 86.

Conclusion: Clinical outcome achieved from physical examination of the knee and the checklist score, suggests that the posterior cruciate ligament avulsion fracture injury is not solely a bone fracture and should be viewed as bone-ligament injury. It seems that operation approach is an appropriate method to improve knee function and reduce the complications.
