@Mr Gary
Please don’t feel that YOU have failed. This is not something you have control over. Your body has a healing rate and capabilities that God programmed into you when He made you.
First of all, you have often said you have little to no pain. That is a huge plus. Many of us, including me at 15 months, still have pain and discomfort.
You are able to do just about everything you want to do. I’m sorry you are unable to kneel to pray. Is that mostly at church, or do you like to pray like that at home? I know God understands, He knows your situation.
It would be nice to do stairs normally, I can’t do them either, it’s very painful for me.
I finally broke down and went for a second opinion. The surgeon I saw came highly recommended. He is a world wide speaker and has even designed his own replacement implants. He knows his craft! One of the first things he told me was, not everyone gets a good outcome, that’s just the way it is, and he said sometimes doing it over makes it worse. He thinks, in my case, my nerves around the knee are damaged and he prescribed gabapentin to see if that helps. I just saw him on Friday so I haven’t picked up the prescription yet.
I hope as time goes on that you and I will continue to improve. Others have done that who were further along than you and I. Time is always on our side.
But if not, we may just have to accept where we are and do the best we can with the outcome our particular body came out with.
If the gabapentin does not work for me I will try one more opinion, but I will not go from dr to dr looking for a solution that may not be out there. Not after one of the best surgeons tells me not everyone gets a good outcome.
Best wishes to you.
