A good exam then MRI: Although most people think a MRI is necessary to diagnose a torn acl, most knee specialists can tell from a couple of simple test that can be done. With a high suspicion, a MRI is often then ordered and used then to confirm the findings of the exam. My suggestion for you is to see a md who is well trained and experianced in acl's and even revision surgery. Get their opinion.

History and physical: Would recommend an orthopaedic history and physical to see if further workup including and MRI to make the definitive diagnosis. For an ACL tear, one most often has a significant injury to the knee with an immediate filling of the joint with blood. Chronic symptoms of ACL tear are giving way of the knee and a persistent effusion.

Depends: Seeing an orthopedist will help answer this question. An MRI would be the most accurate way to determine this, though physical exam may be able to determine the status of your acl.
