What is the anatomy of the ACL?

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. When the knee is extended, the ACL has a mean length of 32 mm and a width of 7-12 mm.

What anatomy is involved in an ACL tear?

These are found inside your knee joint. They cross each other to form an “X” with the anterior cruciate ligament in front and the posterior cruciate ligament in back. The cruciate ligaments control the back and forth motion of your knee.

The ACL, on the other hand, is responsible for preventing the knee from gliding anteriorly. The ACL also stabilizes the knee during movements like bending (of the knee) and the rotation of the knee. On top of this, along with the PCL, the ACL also protects the knee from hyperextension.
