My father-in-law is extremely reluctant to get his knees upgraded to version 2.0. He's in his 70's and has had a recent (last year) bipass surgery. Except for the knee thing he is very active and maintains a highly productive 2 acre garden, of which I enjoy the fruits and wish to continue doing so.

His orthopedic surgeon and cardiologist both tell him he's a reasonable risk and that his life will be dramatically improved.

What convinced you guys to go for it? Would you do it over?

I'm looking for a lever.
