Knee pain. Time to get moving as summer is coming

I had arthro and cortisone on both knees until I was 65. Pain was bad and nothing was helping so I had both knees evaluated and both were bone on bone.
I had total knee replacements in both knees 3 months apart, rehabbed them both and I am able to keep going. Not pain free though, I have age related back issues
effecting both legs. I'm hoping to get another MRI on my lower back soon to see if they can help. No more shots but I know the CBD works for me. Don't use it much
though as I am still working at a RDT company.
