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. There is both an anterior cruciate ligament acl and a posterior cruciate ligament pcl.

The anterior cruciate ligament acl is a band of dense connective tissue which courses from the femur to the tibia.

Knee anatomy acl. The cruciate ligament in the front of the knee is called anterior cruciate ligament or acl and the cruciate ligament in the back of the knee is called posterior cruciate ligament or pcl. Acl anterior cruciate ligament strain or tear. When the knee is fully extended both cruciate ligaments are taut and the knee is locked.

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. During movement of the knee the anterior cruciate ligament acl prevents anterior sliding of the tibia.

Pcl tears can cause pain swelling and knee instability. Gross anatomy the acl arises from the anteromedial aspect of the intercondylar area on the tibial plateau and passes upwards and backwards to. The posterior cruciate ligament prevents posterior sliding of the tibia.

Anterior cruciate ligament acl is one of the two cruciate ligaments that stabilize the knee joint. The acl is one of the primary ligaments providing stability to the knee and therefore is one of the most commonly injured knee ligaments. 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.

The acl is responsible for a large part of the knees stability. An acl tear often leads to the knee giving out and may require surgical repair. Ligaments are tough fibrous connective tissues which link bone to bone made of collagen.

The most common ligament injuries are acl tears mcl tears. Pcl posterior cruciate ligament strain or tear. The anterior cruciate ligament acl is one of a pair of cruciate ligaments the other being the posterior cruciate ligament in the human knee.

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. The acl is a key structure in the knee joint as it resists anterior tibial translation and rotational loads. The acl and pcl are called cruciate ligaments because they form a cross in the middle of the knee joint.
