Anatomy of Posterior Cruciate Ligament November 15 th 2017 Presented by: VC/AY Moderator: WM Supervisor: Dr. dr. Muhammad Sakti, Sp.OT (K)

Introduction PCL is approximately twice as strong and twice as thick as the normal ACL (therefore less commonly injured) The posterior cruciate ligament is located in the back of the knee. It is one of several ligaments that connect the femur (thighbone) to the tibia (shinbone). The posterior cruciate ligament keeps the tibia from moving backwards too far.

origin: - PCL originates from the antero-lateral aspect of medial femoral condyle in the area of intercondylar notch; - It origin is much more anterior than that of ACL insetion: - tibial attachment is not intra articular, but over back of tibial platuea, it is approximately 1 cm distal to the joint line

Anatomy

SUBDIVISION ligament can be partially separated into an anterolateral and posteromedial: anterolateral bundle: - represents about 65% of the substance of the PCL; - in flexion the anterolateral band is tight and the posteromedial band is lax; - most surgeons seek to reconstruction the anterolateral portion of the PCL noting its larger size and more important functional role

COMPOSITION

BLOOD SUPPLY The disk is avascular with capillaries terminating at the end plates Nutrition reaches nucleus pulposus through diffusion through pores in the endplates Annulus is not porous enough to allow diffusion
