Ligamen Posterior Cruciatum Anterior

Anterior Cruciate Ligament Radiology Reference Article

The posterior cruciate ligament (pcl) is a ligament in each knee of humans and various other animals. it works as a counterpart to the anterior cruciate ligament (acl). it connects the posterior intercondylar area of the tibia to the medial condyle of the femur.

The anterior and posterior cruciate ligaments are important stabilizers of knee joint function. although they are both similar in their native appearance, they possess slightly different properties and complement each other in function. the imaging findings differ between the anterior and posterior cruciate ligaments. The cruciate ligaments are intraarticular and also extrasynovial. the acl is an intraarticular structure inserted between the anterior horns of the medial and lateral menisci. originating on the lateral femoral condyle posteriorly and inserting on the anterior tibia. it measures approximately 4 by i. Arises from the posteromedial corner of medial aspect of lateral femoral condyle in the intercondylar notch. this femoral attachment of acl is on posterior part of medial surface of lateral condyle well posterior to longitudinal axis of the femoral shaft. the attachment is actually an interdigitation of collagen fibers & rigid bone thru transitional zone of fibrocartilage and mineralized fibrocartilage. The acl functions to prevent posterior translation of the femur on the tibia (or anterior displacement of the tibia) during flexion-extension of the knee. the amb is responsible for the posterior translation of the femur at 30 degrees flexion, and the plb resists hyperextension and prevents posterior translation of the femur in extension 1, 2.

There are two components of the acl, the smaller anteromedial bundle (amb) and the larger posterolateral bundle (plb), named according to where the bundles insert into the tibial plateau. the anteromedial bundle is tight in flexion and the posterolateral bundle is tight in extension. in extension both bundles are parallel; in flexion the femoral insertion site of the posterolateral bundle moves anteriorly, both bundles are crossed, the anteromedial bundle tightens and the posterolateral bundl

The acl has a microstructure of collagen bundles of multiple types (mostly type i) and a matrix made of a network of proteins, glycoproteins, elastic systems, and glycosaminoglycans with multiple functional interactions. The acl provides approximately 85% of total restraining force of anterior translation. it also prevents excessive tibial medial and lateral rotation, as well as varus and valgus stresses. to a lesser degree, the acl checks extension and hyperextension. together with the posterior cruciate ligament (pcl), the acl guides the instantaneous center of rotation of the knee, therefore controlling joint kinematics. while the anteromedial bundle is the primary restraint against anterior tibial transla 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. Ligamen cruciatum posterior (posterior cruciate ligamen, pcl) adalah ligamen yang berada di lutut. seperti halnya ligamen cruciatum anterior (acl), pcl menghubungkan tulang paha (femur) dengan tulang betis (tibia). pcl berada di bagian belakang lutut. pcl menjaga tibia agar tidak bergerak ke belakang terlalu jauh.

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 2 ligaments are also called cruciform ligaments, as they are arranged in a crossed formation. Anterior-posterior, lateral, tunnel, and sun-rise views, should be the initial imaging study to assess for fractures, evaluate knee. table 1. contributing mechanisms to acl injuries.

The major blood supply of Ligamen Posterior Cruciatum Anterior the cruciate ligaments arises from the middle geniculate artery.   the distal part of both cruciate ligaments is vascularized by branches of the lateral and medial inferior geniculate artery.   the ligament is surrounded by a synovial fold where the terminal branches of the middle and inferior arteries form a periligamentous network. from the synovial sheath blood vessels penetrate the ligament in a horizontal direction and anastomose with a longitudinally orientated Oct 15, 2010 · anterior-posterior, lateral, tunnel, and sun-rise views, should be the initial imaging study to assess for fractures, evaluate knee. table 1. contributing mechanisms to acl injuries.

The anterior and posterior cruciate ligaments are complex. the anterior cruciate ligament starts in the anterior aspect of the tibia in the joint space and goes up to the back of the joint space on the femur. The acl receives nerve fibers from the posterior articular branches of the tibial nerve. these fibers penetrate the posterior joint capsule and run along with the synovial and periligamentous vessels surrounding the ligament to reach as far anterior to the infrapatellar fat pad.   most of the fibers are associated with the endoligamentous vasculature Ligamen Posterior Cruciatum Anterior and have a vasomotor function. the receptors of the nerve fibers mentioned are as follows: 1. ruffini receptors which are sensitive to stretchin Oct 14, 2020 · the anterior and posterior cruciate ligaments are complex. the anterior cruciate ligament starts in the anterior aspect of the tibia in the joint space and goes up to the back of the joint space on the femur.
