I have RA, diagnosed at Christmas 2020.
I also have buggered knees - I believe that is the correct medical term - that pre-date the RA diagnosis. At my last (final?) RA consultation the consultant showed me a beautiful X-ray of my knees.
Nice bones, absent cartilage. He had previously mentioned knee surgery, to be considered after stabilising RA, which seems very successful so far, allowing for the loss of strength and stamina.
I had never been keen having watched others struggling with two long sticks. However, they are getting worse.
At that date, Autumn 2021, the waiting time would have been 4 years. I was then 82, now 85.
It scarcely seems cost-effective, given an apparent shortening of life expectancy with RA.
I wonder if there is any other way to alleviate the pain in buggered knees? They are inhibiting.
