Well. As a contribution to keeping this thread near the top I'll report on my new hip, which is now 15months old. {grin]
I'm sorry to hear from grammargran that she doesn't feel quite 'bonded' to her new hip, but I am delighted with mine. Though I suspect that, in my mid 70s, I'm a bit younger than her).
I did have an ambition in mind, which was to be able to ride a horse again and I did work hard at getting my leg muscles back into accepting the right 'position' for riding and redeveloping the strength needed in the operated leg. Walking 'was' a great help and made more easy to accomplish by being part of a local Ramblers group (which, incidentally, has a fair quantity of artificial hips and knees among its membership).
Pilates helped too.
Before my op walking, even with two sticks, was really difficult and painful and, while driving wasn't too bad, getting in and out of the car was painful. Sleeping was hard, too because of the constant pain from the hip, which not only affected the hip but travelled around my leg, too. There was a particularly nasty pain in my shin, of all places, which I had to put ice packs on to relieve.
All that has gone now, I don't think thee is anything that I can't do now that I could do before the hip deteriorated.
For those who might be fearful of falling, my hip has survived a few minor falls and a quite serious accident in the summer.
This is just my experience of course and everyone is different, but for me it has been positively life changing.
