When the knee is fully extended both cruciate ligaments are taut and the knee is locked.

Knee anatomy acl. In knee joint anatomy they are the main stabilising structures of the knee acl pcl mcl and lcl preventing excessive movements and instability. Acl anterior cruciate ligament strain or tear. The anterior cruciate ligament acl is a band of dense connective tissue which courses from the femur to the tibia.

The acl is a key structure in the knee joint as it resists anterior tibial translation and rotational loads. The acl is responsible for a large part of the knees stability. Ligaments are tough fibrous connective tissues which link bone to bone made of collagen.

There is both an anterior cruciate ligament acl and a posterior cruciate ligament pcl. The anterior cruciate ligament acl is one of a pair of cruciate ligaments the other being the posterior cruciate ligament in the human knee. Pcl posterior cruciate ligament strain or tear.

The posterior cruciate ligament prevents posterior sliding of the tibia. Cruciate ligaments this group of ligaments present inside the knee joint control the back and forth motion of the knee. The 2 ligaments are also called cruciform ligaments as they are arranged in a crossed formation.

The anterior cruciate ligament acl is one of a pair of ligaments in the center of the knee joint that form a cross and this is where the name cruciate comes from. Anterior cruciate ligament acl resists anterolateral displacement of the tibia on the femur resists varus displacement at 0 degrees of flexion posterior cruciate ligament pcl. Pcl tears can cause pain swelling and knee instability.

An acl tear often leads to the knee giving out and may require surgical repair. The most common ligament injuries are acl tears mcl tears. During movement of the knee the anterior cruciate ligament acl prevents anterior sliding of the tibia.

The acl is one of the primary ligaments providing stability to the knee and therefore is one of the most commonly injured knee ligaments.
