I had the Iovera treatment in September 2024. I wound up not having the surgery due to other reasons. I suffered greatly from just the Iovera and can't imagine the pain from that along with the pain from the surgery. I am not talking about the pain when I received the treatment, this is the pain within a week after receiving it. I am still numb but the nerve pain has subsided. I could not stand even a sheet touching it until lately. So no, I will not have it again if I ever decide to go through with the TKR.
