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
Fibrous joint joint, form the only non-sutured joints in the skull. Most sutures are named for the bones they articulate, but some have special names of their own. A syndesmosis is a slightly movable fibrous joint in which bones such as the tibia and fibula are joined together by connective tissue. Examples include the distal tibia fibular joint as well as the radioulnar joint. Injuries to the ankle syndesmosis are commonly known as a "high ankle sprain". Although the syndesmosis is a joint, in the literature the term syndesmotic injury is used to describe injury of the syndesmotic ligaments. It comes from
