I had a hip replaced in February of this year and I think the recovery time is longer, but as others have said the PT part is crucial.
I've heard other guys say that they didn't follow orders and things aren't good. I found that MENTALLY the exercises seemed kind of "stupid". "How's that little move going to help?" Then, I found some of them hard to do! Do the work and MOSTLY it'll be good.
At least the pain is gone, replaced with stiffness and less range of motion, but I'm only 6 months out. Hips are supposed to be 8-10 months, knees(I've been told) about 4 months.
You think an all day hunting sit is tough until you put in MONTHS waiting...
But everyone that's had them is back at it in the required time. As my wife says when I'm whining, "Is it better than before the surgery?" Oh Yeah!
