The anterior cruciate ligament (ACL) is one of a pair of cruciate ligaments (the other being the posterior cruciate ligament) in the human knee. They are also called cruciform ligaments as they are arranged in a crossed formation.
The ACL is the big ligament that keeps your knee stable as you run and jump. Athletes sometimes suffer a torn ACL. It's one of the worst sports injuries. That's because unlike other torn ligaments, the ACL won't completely heal. The ACL does heal.
