Great to hear your wife has gumpsion (as they say in Maine)
I myself broke a hip back in the late 70's but tried never to slow down but by the late 90's the pain was so great I was forced to give up alot of things I loved, one of them hikeing and camping, but never lost my love of the outdoors and with the help of others would go fishing.
3 years ago I had a complete hip replacement and I think that the pain I went though the last 7 years makes any pains I get with the replacement really nothing.
I hate to see people who just give up
so get out there and enjoy the things you love to do
