How do knee ligaments work?

ANSWER

The anterior and posterior cruciate ligaments are in the center of your knee. The ACL is toward the front of your knee. It controls forward movement and rotation of your shinbone.

The PCL is toward the back of your knee and controls backward movement of your shinbone.

The MCL is on the inside of your knee and gives that area stability.

The LCL is on the outside of your knee and keeps the area around it stable.
