Hello all I am desperate for opinions. In 2009 I injured my left knee skiing and authorized my OS to due an ACl recon and meniscus "clean up". MRI said I had a complete tear of the ACL. Dr. told me I had a false positive and that ACL was mostly in tact. I did PT and moved on (ran 4 marathon's and skied fine from recovery until Thanksgiving day of 2013). On that day I was running on uneven surface and "tweaked" my knee. Went back to Dr. who then confirmed through physical exam that it was now fully torn. A second Dr. months later confirmed that. I can ski if I take it easy and I can run but have not attempted anything too far. Knee bothers me a bit walking up stairs or sometimes in yoga. Anything single legged (like a single leg squat) is quite difficult but the knee doesn't buckle. I've tried PT and I guess I could live with this but Dr. says unless I get ACL reconstructed I'll never be the same and further more susceptible to further injury without an ACL. I'm torn because clearly this is an elective procedure but I just want two good knees. What would you do at this point?
