How does Anterior cruciate ligament work? Please explain the biomechanics involved.

Question

anonymous · Answer

The biomechanical properties of the ACL are determined by the geometry of the ligament as well as the tensile characteristics of both ligament mid-substance and the ligament-to-bone insertion site.

anonymous · Answer

Basically, they can be characterized by the relationship between ligament length and ligament tension, which can be determined when simultaneously measuring load and the corresponding elongation during experimental uniaxial tensile testing. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2321720/ (use this link if you need anymore information) :)

bro. The anterior cruciate ligament (ACL) extends from a broad area anterior to and between the intercondylar eminences of the tibia to a semicircular area on the posteromedial portion of the lateral femoral condyle. It not only prevents anterior translation of the tibia on the femur but also allows for normal helicoid knee action, preventing the chance for meniscal pathology.
It is composed of two bundles that are named based on their relative attachments on the femur and tibia: an anteromedial bundle, which is tight in fl exion, and a posterolateral bundle, which is more convex and tight in extension

Yeah but they asked for the biomechanics :p
