As one who experienced essentially what you describe some years ago, I enjoyed your report and wish you well.

I tried to reenter martial arts with aikido at about your age but found that my knees could not take the pressure-subsequently titanium has replaced bone.

All the best.

I still have certain warm up exercises I cannot do, mostly the weight bearing ones, but I try to negotiate with the Senei (instructor) of that day. I can still do some grappling, using a lot of upper body strength.

Now that I'm older and a little wiser, I'm more inclined to study the art of "fight without fighting"

And I also carry a cache of weapons on my person.
