In brief: Swelling

The best indicator that an acl tear has occurred is that shortly after the initial injury, an effusion (knee swelling within the joint) occurs.
It occurs rapidly and usually fills up the joint. This occurs because of the bleeding involved at the time of injury. Other signs such as instability are hard to judge and warrant careful attention.
