I only ask because the doctors I have seen are so reluctant to do any surgery on my knees because of my age. They say that for me, doing TKR at 60, they would not want want to do a revision if needed at 85. They want me to wait ten years till I am 70 so I would be hopefully (for them) dead before another revision. I find it so very bizarre as I can do nothing and am in constant pain. I don't know if they just don't believe me or what. I find the lack of empathy with these doctors astonishing. The only thing I can do is sit in my recliner and watch tv or use my laptop. I can't do my graphic design business on my desktop computer because it hurts so much to sit there, and I can't be as accurate, intricate or intensive on the laptop as I need to be (though I do give it quite a good try). I can't work and I don't see myself re-starting my career at 70 after they finally agree to do my knees, ha! I would like to be able to work my last 5 to 10 years before retirement. I've done so much reading here and I see people of all ages in all circumstances with success. I wonder if the hospitals have statistics about the age of TKR's.
