Introduction[edit | edit source]

Anterolateral-Ligament.jpg
The Anterolateral Ligament of the Knee (ALL) is described as a distinct ligamentous structure at the anterolateral aspect of the knee in 2013[1]

Attachments[edit | edit source]

Origin[edit | edit source]

The prominence of the lateral femoral epicondyle, slightly anterior to the origin of the lateral collateral ligament. Connecting fibers between the two structures have been observed.

Orientation[edit | edit source]

Oblique course to the anterolateral aspect of the proximal tibia, with firm attachments to the lateral meniscus, thus enveloping the inferior lateral geniculate artery and vein.

Insertion[edit | edit source]

On the anterolateral tibia, grossly located midway between Gerdy's tubercle and the tip of the fibular head. Definitely separate from the iliotibial band (ITB).

Nerve Supply[edit | edit source]

Vascular Supply[edit | edit source]

Composition[edit | edit source]

Function[edit | edit source]

Given its structure and anatomic location, the ALL is hypothesized to control internal tibial rotation and thus to affect the pivot shift phenomenon.
