Anterior Cruciate Ligament (ACL) - Physiopedi

  1. 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
  2. Gross anatomy. The ACL arises from the anteromedial aspect of the intercondylar area on the tibial plateau and passes upwards and backwards to attach to the posteromedial aspect of the lateral femoral condyle. Like the posterior cruciate ligament, the ACL is intracapsular but extrasynovial. The ACL consists of two components 4: anteromedial bundle (AMB
  3. Main results: Anterior cruciate ligament injuries occur more commonly in women than in men due to a variety of anatomical factors. The ACL consists of 2 major bundles, the posterolateral and the anteromedial bundles. Forces transmitted through these bundles vary with knee-joint position
  4. ACL stands for the Anterior cruciate ligament, also known as interior cruciate ligament. It is a band of dense connective tissue that connects the femur (thigh bone) to the tibia. Define the term 'cruciate'
  5. AbstractThe anterior cruciateligament (ACL) is a band of denseconnective tissue which courses fromthe femur to the tibia. The ACL is akey structure in the knee joint, as itresists anterior tibial translation androtational loads. When the knee isextended, the ACL has a mean lengthof 32 mm and a width of 7-12 mm.There are two components of theACL, the anteromedial bundle(AMB) and the posterolateral bundl
  6. MOB TCD Articular Surfaces • The femoral articular surfaces are the medial ACL and lateral femoral condyles • The medial condyle has a longer articular surface • The superior aspect of the medial and lateral tibial condyles • The posterior aspect of the patella 7
  7. 1.1 Anatomy and Normal MRI Appearance. The ACL extends from the posterior part of the medial aspect of the femoral condyle to the anteromedial tibial plateau. The normal sagittal angle between ACL and the tibial plateau depends on patient's age and gender. The mean sagittal angle between ACL and the tibial plateau in adults is between 54.

Anterior cruciate ligament labeled at center left. 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 two ligaments are also called cruciform ligaments, as they are arranged in a crossed formation ACL is an intra-articular extrasynovial structure. Its mean length is 38 mm and width is 11 mm. Its fibers run in a spiral fashion for the entire length. Volume of ACL is larger in men than women, in proportion to the difference in height
