See below: Symptoms of an acute tear of the acl include swelling of the knee, severe pain, often bruising seen as black and blue marks on the knee and a knee that may feel unstable and will feel like it will give way. Right after the injury, it may be hard for a doctor to make the diagnosis because of the swelling. The physical exam after the swelling has gone down and usually an MRI will confirm.

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.
