I got on
the forums because I fear I have reinjured my ACL
. I tore it about 7 years ago. This time, I heard the loud "pop" sound and it was deja vu. I just knew and the ER doctor confirmed. However, after seeing an orthopedic surgeon, he said otherwise. He seemed to think maybe I tore some cartilage but nothing turned up on the MRI. The Lachman's test, he said, did not show much disturbance in my ACL.
