When refering to evidence in academic writing, you should always try to reference the primary (original) source. That is usually the journal article where the information was first stated. In most cases Physiopedia articles are a secondary source and so should not be used as references. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article).

Basic Structure and Function[edit | edit source]

The PCL is a very large ligament, located posterior to the ACL, comprised of 2 bundles:

Anterio-medial: taught when knee is in flexion
Posterio-medial bundle: taught when knee is in extension

Both bundles work synergistically to create stability within the knee.

Functions:

PCL is the primary restraint to posterior translation of tibia relative to femur
Secondary stabilizer resisting tibial external rotation as well as valgus/varus stresses

It often occurs in combination with other ligamentous damages.

The mechanism of injury involves some type of varus or valgus force in combination with posterior tibial force.
