Force: An acl injury usually is a rotational or hyperextension force applied to the knee causing mechanical failure of the ligament. People get these injuries as a result of being fatigued, out of shape or are just in the wrong place at the wrong time.

Pivoting on leg.: Twisting or pivoting of your lower leg, while having your foot planted can cause an ACL injury. For example, a football or basketball player plants his/her foot to change direction, and feel their knee just give out on them. That's the classic mechanism for an ACL injury.

Are vascular conditions a common complication of injury?

Vascular conditions after an injury are not uncommon; they often are missed because they're not suspected and don't have symptoms right away. A missed vascular condition after injury can be devastating. If you are injured, ask your doctor to evaluate you for a possible vascular condition.
