Re: Ruptured ACL
Years of instability, due to a ruptured ACL, have likely led to further joint damage. This is why it is recommended to have ACL surgery soon after an ACL injury - so you can regain leg stability. I can't see why you would avoid surgery at this point - I'm surprised no physician has encouraged this earlier.
