Posterior cruciate ligament the tibia. The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement. It originates from the lateral edge of the medial femoral condyle and the roof of the intercondyle notch then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface. Although each PCL is a unified unit, they are described as separate anterolateral and posteromedial sections based off where each section's attachment site and function. During knee joint movement, the PCL rotates such that the anterolateral section stretches in
Stifle joint the joint into two functional units—the 'femoromeniscal joint' for flexion/extension movements and the 'meniscotibial joint' for rotation—a function analogous to that of the disc dividing the temporomandibular (jaw) joint. The menisci also contain nerve endings which are used to assist in proprioreception. The menisci are attached via a variety of ligaments: two meniscotibial ligaments for each meniscus, the meniscofemoral from the lateral meniscus to the femur, the meniscocollateral from the medial meniscus to the medial collateral ligament, and the transverse ligament (or intermeniscal) which runs between the two menisci. There are between one and four sesamoid bones associated with the
