I, also, have been diagnosed with the big N. Have had it for many years and the last five or so have been wicked. I also have a very bad knee which was going to be replaced and then the pandemic stopped all elective surgery. At that time I started using crutches to get around. To me that was much easier and more convenient than a walker and easier to manipulate in tight quarters, etc. and I just stuck with that method of assisted movement. I also cannot put much weight on the knee because of the pain. Stepping down on that foot while using a walker would be of no help to my pain level. I have quite a bit of numbness, too so replacing my knee at this time doesn't make much sense . I am soon to be 84.
I find crutches and a very handy way for me to get around, take up much less space, and are easily manipulated to get me where I painfully need to go. I do need to keep up with upper body exercises to be able to use my crutches every day as I do, as well as others for my Neuropathy.
I have a friend who also uses crutches as her main form of locomotion and has her pair all tricked out! Her kids bought her a pair that look like tree branches and she decorates them for the seasons....quite a sight! Helps get us both through some rough days, I tell ya!!
