I feel for him! Both my knees swell and are so painful with OA. Left one was offered TKR three years ago but I prefered exercises which have really helped (much to my surprise) until now, I think it has all deteriorated. Right knee is in a dodgy leg! I’ve had three hip replacements (yep) and they are a doddle in comparison to TKR, a very painful operation for most people and lots of rehab and a 20% regret rate and better done late as possible but not too late to do the healing. Awful decision.
My surgeon held the opposite view -if it is REALLY necessary it’s best done as early as possible, because younger people heal so much quicker and they will get so much benefit from the operation. I was only 59 and could barely walk, the pain in both sides was very bad, my work & social life was virtually over. X-rays showed both knees to be bone on bone and wearing thinner all the time. He said these days the replacement knees should last 30 years, so with eleven months apart I had bilateral replacements. I have never looked backed, I go hiking in the Lakes, I’ve been to the top of Snowdon, I climb all the church & cathedral towers when on holiday, I do keep fit classes etc - so my health is so much better as I’m not sitting around.
If the operation is just not possible then I recommend a good knee brace, a physio should be able to advise.
