The posterior cruciate ligament keeps the tibia from moving backward with relation to the thigh bone.Together with the posterior cruciate ligament (PCL), the ACL guides the instantaneous center of rotation of the knee, therefore controlling joint kinematics.

Both ACL injury and PCL injury may present initially as acute internal knee derangement, reducing the yield of physical examination maneuvers. The diagnosis is typically confirmed via MRI, which can have variable findings depending on the mechanism and associated injuries. Lachman’s test is an alternative test assessing for laxity or rupture of the anterior cruciate ligament (ACL).
