I found a website that has an incredible
about of insight on the way the ACL works, looks, functions, etc. I have
provided the link below, also the site contains diagrams that have taught me
tons. Upon creating my website and presentation, this site is a definite
go to.
As I've already explained, the ACL typically tears due to sudden
stops, turns, decelerations or hyperextension of the knee. It is
also the knee stabilizer. In addition to provide a short back ground of the
knee, the knee joint is formed by the femur, tibia and patella and held
together by the medial collateral, lateral collateral, anterior cruciate (ACL),
and posterior cruciate. The anterior
cruciate runs diagonally in the middle of the knee. The positioning of every ligament provides a
stabilization and important factor in the knee. Also, about half of the ACL
injuries are in combination with MCL or other ligament damage.
