Can massage therapy help an acl/mcl sprain or tare?

Perhaps. Massage may be helpful to deal with any swelling associated with an acl/mcl sprain (which is the same as a tear) and it may help to mobilize inflammatory byproducts and increase blood flow to the injured area. It is not a stand alone treatment and should be part of a more general rehabilitation program that may or may not include surgery if the tear of the acl is severe.
Massage for sprain. Not likely to help. Better to see your physician for treatment options.
