Abstract
The PCL is approximately twice as strong as the anterior
cruciate ligament (ACL) and represents the strongest
ligament of the knee, which plays an important role in
stabilizing the knee joint.
A rupture of PCL often leads to an increased posterior
tibial translation with full laxity at 90 degrees of flexion
and a small rotation or lateral instability. This results in
posterior subluxation of the tibia, wherein an abnormal
pressure on the in medial and patellofemoral
compartments, is created, leading to chronic pain and early
cartilage degenerative arthritis and increased risk of
meniscal tear.
Due to its strong fibers structure, PCL ruptures are
less frequent than ruptures of other knee ligaments. An
avulsion fracture of the PCL usually occurs in a small
subgroup of PCL injuries where is tibial avulsion fractures
are more common than femoral avulsion fractures.
