Brief study on posterior cruciate ligament

The knee is made up of a complicated arrangement of osseous and soft tissue components that work together to provide three planes of motion. The knee is stabilized by both dynamic and static stabilizers. The knee ligaments, which are static stabilizers, play an important role in maintaining knee stability across the complete range of motion. The Posterior Cruciate Ligament (PCL), like the Anterior Cruciate Ligament (ACL), is one of two cruciate ligaments in the knee. The PCL has a significant role in limiting posterior tibial translation in relation to the femur. In addition, the PCL functions as a supplementary constraint around the knee, preventing varus, valgus, and external rotation. Injury to the PCL can develop from a posterior force placed on the tibia, most commonly with the knee in a flexed posture, albeit it is less common than ACL injuries. In order to correctly evaluate, diagnose, and treat PCL injuries, clinicians must have a thorough understanding of the anatomy and biomechanics of the PCL.
