A positive Lachman test is often seen in an ACL tear. ACL tears -generally the swelling occurs more rapidly than meniscus. A positive Mcmurray sign is a good indicator of meniscal tear. At the time of the injury of an ACL tear, often a pop is heard (70% of the time according to epocrates). Although every patient is different, rapid swelling of knee, an audible pop at time of injury, and a positive lachman, are all good indicators that there is an ACL tear.
