I had TKR in 2020. It was done by a top Boston doctor. To this day, my replaced knee is still very sensitive and sore. I cannot kneel down on that knee and it almost feels like I have arthritis in it. My left knee is very bad but I go for cortisone shots for it every three months and those shots give me great relief. My recovery from that right knee replacement several years ago was BRUTAL and I will not ever go through that again! I was in such pain (the pain meds they gave me were ineffective or I broke out in a rash from them). I could only take Tylenol. I have to admit that I was so depressed at my lack of progress in the healing process. I do all of the exercises every other day to keep up the strength in my muscles. So, I will continue to do my exercises, and go for the cortisone shots, but I will never have another knee replacement!!! I had to do PT twice a week for six months to get back to feeling “somewhat normal” again!!!
