I am 42 years old and very active. I run and workout 5 times a week. I tore my acl snowskiing. I am scheduled for a cadavar graft in a few weeks. I have spoken to many people who have had this problem. I get many diffierent responses to my questions even my doctor. What happens to my knee years down the road if I do not have the reconstruction?, I am at around 90% now. I have a few issues, but I think I can live with them. Will I do more damage to myself down the road if I don't have surgery? Help please.
