INTRODUCTION - The posterior cruciate ligament (PCL) is a crucial component that helps keep the knee stable during flexion and rotation. Because the PCL is so robust, avulsion fractures at the PCL's attachment location are common. For complete restoration of PCL function, it is generally believed that avulsion fractures of the PCL should be anatomically reduced and fixed. Conservative therapies usually result in unsatisfactory outcomes, primarily due to functional disability and fracture non-union. Many surgeons think that the displaced or unstable tibial avulsion fracture of the PCL should be reduced and repaired anatomically using various techniques
