What is Posterior cruciate ligament?
The '''posterior cruciate ligament''' ('''PCL''') is a [[ligament]] in each [[knee]] of humans and many other animals. It works as a counterpart to the [[anterior cruciate ligament]] (ACL). It connects the [[posterior intercondylar area]] of the [[tibia]] to the [[Medial condyle of femur|medial condyle]] of the [[femur]]. This allows the PCL to resist forces pushing the tibia posteriorly relative to the femur. The PCL gets its name by attaching to the posterior portion of the tibia.<ref>Saladin, K. S. 2010.
