• The anterior cruciate ligament (ACL) originates on
the posteromedial aspect of the lateral femoral
condyle. From there, it courses anteromedially to
insert in a wide, depressed area just anterior to and
between the intercondylar eminences of the tibia.
• The ACL is approximately 33-mm long and 11-mm in
diameter (Miller, 2000). The blood supply is from the
middle geniculate artery. Innervation is via branches
of the tibial nerve.
• Often described as having two distinct bundles. The
anteromedial bundle is tight in flexion. The posterolateral
bundle is tight in extension.
• The primary function of the ACL is to resist anterior
translation of the tibia on the femur. Secondary functions
include stabilization against excessive varus and
valgus stress, stabilizer to hyperextension, proprioception,
and the screw home mechanism.
