The Posterior Crucilate Ligament or PCL is two times thicker than an ordinary ACL and these are lesser chances or risks of PCL injury. While the breadth is 13 mm almost, the length is equivalent to that of an ACL. The PCL emanates from the posterior position to the front and lies opposite to that of ACL.

Although, the injury of PCL does not cause as much pain and inflammation as compared to ACL, it may take weeks before one can expect get a recovery from this injury.

The major reasons for this injury are the collision of the lower bone or tibia with some hard surface or object, the next is a major fall on the knee whole playing the game of soccer or the last thing can be an injury due to bad movement or due to losing balance.
