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.

Examination by an: Orthopaedist is key. We can often tell by exam only. An MRI can be used to confirm the diagnosis. People typically complain of instability in the knee or "giving out" especially with side-to-side movements or twisting of the knee. The knee is typically swollen and can be stiff. Pain can vary from severe to minimal.
