I actually still have a 28" running vert, as measured yesterday. Surprisingly, it doesn't hurt much unless I land with that foot, but I land only on my left foot. I am unable to run though without severe pain. PT hasn't really improved anything though for obvious reasons. I had a friend who waited 8 months after an acl tear to repair it and he was walking fine after 1-2 months. I don't think full ligament tears hurt as much as partial tears because there is nothing being irritated.
