In brief: Effusion (swelling)
An acl tear can often include an mcl tear that occurs at the same time.
An acl tear generally causes bleeding in the knee joint caused by tearing the blood vessels around the acl. This causes a very fast swelling of the knee joint (usually without the hour). An isolated mcl tear usually does not swell inside the knee and causes pain on the inner portion of the knee, where the mcl tore.
