I used a walker in the hospital, and had both a walker and crutches at home. When the phsical therapist came to my home the first time, he asked me why I was using a walker instead of crutches, and said crutches are best because a walker tends to force you to lean forward a bit which is not as helpful in getting back to a normal gait. When I had the other hip done, I ignored the walker, used two crutches, then one, and now none.
By the way, for those that have recently had the surgery and are still on two crutches, my PT also gave me another little tip that helped me a lot. We have a lot of stairs in our home, and I never did feel all that secure at first going up and down using two crutches. He suggested that just before I start going up or down that I use the handrail for one hand, and the extra crutch can be carried along with the other hand, perpendicular to the other crutch, so it makes a big plus sign. I felt much more secure this way on stairs, and still had the other crutch for when I got to the top. Anyway, just my $.02 worth.
Congrats to you that have made it through your surgery and are on the road to recovery. My right hip is almost 9 weeks post-op, and I can tell it is very strong and has just a little muscle pain now and then (still healing). The left side is almost 4 weeks post-op, and although I have been walking unassisted for about a week and a half, I walk like a penquin because the muscle still needs quite a bit of strengthening. I still can't get over how great it is to have no arthitis pain!!!
