I don't know who you saw but I am guessing it is not a board certified surgeon. Did he happen to tell you how severe her arthritis will be if you don't repair this torn ligament? She is looking at a lifetime of pain.
I understand it is expensive, but I highly recommend that you get her to a boarded surgeon and find a way to get the money together for her care. Look at things you can sell. Ask family for help. Try to get a credit card from
