Thank you for those kind comments, It's True, it would be drastic and I will definitely get another opinion before I have any amputation.
The problem is the Neuropathy has damaged my bones (I'm told) which is why they were trimmed during each TKR. IMO, after 4 failed TKR's (still on #4 but it's time is limited) I think the surgeon's have given up on the idea of getting a TKR to work for me. Now that my Tibia is short, my present surgeon suggests he replace my (good) hip and run a rod between my hip and ankle. I will be unable to bend my leg at all but we avoid amputation. Lots to consider. I'm not seriously considering that option though. It would require probably 2 major surgeries which I don't want my wife to suffer through or me. ,
As Far As the way the docs act after the TKR, in my case I saw that. It was very subtle and may have been my imagination but I sensed a change.
As things are now I'll probably keep getting around on my walker trying to get my legs stronger and hopefully things will improve.
Thanks again,
Larry
