What are sprained and torn ACLs and PCLs?

ANSWER

An anterior cruciate ligament (ACL) injury is a common sports injury generally caused by a hard stop or a violent twisting of the knee. The posterior cruciate ligament (PCL) is stronger than the ACL and doesn't tear as often. A PCL injury�may happen with a serious blow, such as when the knee strikes the dashboard in a car accident. If you tear your ACL, you may hear a pop. You will also notice your knee give way or become unstable and feel extreme pain.
