Sue, I would say you need to get off your butt and start using your knee more.
I weigh a heck of a lot more than you do probably, and walking is very hard for me and I have to work at it, but I do a lot of the exercise that I can do, the bike, the pool and weights, and just keep working at the walking in baby steps. If I let myself, I would go up the stairs one at a time, but I make me go up normal, same with down. I really believe in the "use it or lose it" philosophy. I think if you carry any extra weight going into this surgery, it makes it that much more harder to recover and regain strength because one is already carrying more weight to begin with. If I do not exercise and stretch almost daily, my knee gets stiffer and the tissues feel a "tearing" sensation. But if I do some exercise each day, everything works better in the knee and I am able to use it better and better all the time. But if I did not exercise I think it would be a mess.
You might be having a slower recovery than others, but that is not a reason to not exercise the knee. My recovery is slower than others, I can't walk much due to the other knee and some hip issues, but I do make small gains, and my other exercise stuff is almost back to pre-surgery. Personally, I believe that if you keep babying the knee it will become a permanent habit and you will keep on babying it. Many PTs and doctors and athletic specialists believe this and I do too, also from personal experience with other injuries. I am sure there are many other people on the forum who will disagree. But the question I would pose to you is, what you are doing now is not working that well for you, based upon what you have posted and you aren't particularly happy with where you are it, are you? Then to me that says you need to try something different for awhile and see if things change. I don't know what kind of motivation will help you exercise, getting a trainer, joining a group, writing down an exercise regime, getting some more PT and I don't know what your options are, you will have to identify those things for yourself, especially since you are in France and I have no idea what is available.
Hope that was not too much of a boot camp kick-in-the-pants post! FWIW, support is key when doing something that is hard for you or you don't like doing. Find an exercise buddy if you can or a group of women to go for a walk with and complain about your husband(s)/kid(s) with. I know it is not easy, but I think you knee will love you for it.

That's a lot to ask for, isn't it?, a little too much pressure on ones self, I think! If I wanted to feel 50 at 64, heck I'd be in the dumps all the time!
I'm so happy I don't have excruciating pain 24/7 day or night, that whatever happens after that is cake, so to speak! Enjoy what you have at the moment and the rest WILL come my friend!
And obviously he hasn't learned the "The customer is always right!", silly man!
And as you said "Il va venir..." it will come!
