I’m 74 - new knee 2 years ago.
miserable operation and rehab but 100% would do it again.
Ditto. Both of my knees were replaced four years ago. They are a huge improvement. I could not walk more than one hundred yards without nauseating bone on bone pain. Now, my walking range is painless and unlimited. However, I believe that the surgeon’s skill is the critical favor, as one knee is slightly better than the other.
