One knee replacement and will never have another one!

Hello to all of my fellow knee sufferers! I had a TKR in 2020. I had a very rough time after the surgery…..allergies to pain meds etc and had to only take Tylenol! PT for six months following surgery. My knee (right) is still painful and stiff, even after the replacement. I had this done at a top Boston hospital with a surgeon that came highly recommended. However, his answer to me with all of this pain and stiffness is “It will never be the knee that God gave you.” Oh, great!!! My left knee is bad but I could never go through this surgery again. I have had cortisone shots to the left knee which are no longer working and recently received three gel shots, which did not help. Both of my knees are so painful! Should I seek out a dr who deals with pain? I don’t know what else to do. Other than these knee issues, I am in good health and am 75 years old (although, other than these knees, I don’t feel like I am 75!!!!). Any suggestions or help would be deeply appreciated! I have tried knee braces, creams, ointments, Voltaran, Advil, Tylenol etc. Nothng has helped!!! Thank you, in advance, for any input! MaryAnn from Boston
