Surgeons like to cut, it is why they became surgeons. Find a surgeon with a significant waiting list so she has no financial incentive to cut you.

I do somewhat disagree with @andid regarding timing. Many who get TKRs suffer severe pain but others (such as me) don't suffer at all. One can take steps to maximize one's chances of being pain free or pain minimized. I was prepared for pain post surgery because I had been having pain, some severe, for nine months. So recovery pain was a doable and sufferable alternative but I did research to find an experienced surgeon who could do a subvastus or midvastus approach and do a Functional Alignment to take care of my severe valgus misalignment.

The relief from ongoing pain is incredible. But I have to admit that I am one of the outliers who had no post surgery pain. Would it have been worthwhile if I was an outlier on the other end of the scale? I think so but it is easy for me to say that.
