I had ACL revision surgery because my 1st had failed, Lachmann test showed it had but MRI said it was intact, when they went in it had ruptured? And now 3 months post op I m getting intense pain on the medial side of my knee and it is giving way a lot, my pt and surgeon both think it is either stretched or re ruptured, this is after the Lachmann test also, I was sent for a MRI again, and it is again saying all is ok, but all my other symptoms a pointing towards another fail, could the MRI be giving a false reading, I do have a few screw in my knee from the surgeries, the pain is waking me at night too
