I saw a slight variation on my first (bone on bone for about a year or so) and my second (slight bit of cartilage left). I think it may have been due to some of the technology used for each and the state of my hip (sounds like a presidential address... four score and seven months ago... my hip started to kick my.... ).
My left hip was bone on bone, I was out of the hospital in three days, the recovery was longer partly due to a drain being put in which needed to heal along with my incision; the hip itself, though had no restrictions and I was exercising and weight bearing as soon as possible. recovery to unassisted was about five weeks, to one crutch about a week, driving in two, showering in one. Back to work in five weeks.
My right hip still had cartilage, I was out of the hospital in two days, because of a new type of bandage (to me), a silver flat, water resistant bandage, I was able to shower right away. Walking unaided was bout the same, about five weeks (maybe four), to one crutch in a week, driving in two, despite the fact that this was my right (no issues with motion of the foot from accelerator to brake and back). Back to work in five weeks.
So the recoveries were essentially the same, much less swelling from the second, but I attribute that to the amazingly good silver bandage and not having any stitches / sutures / steri strips the second time around, just the bandage and glue.
Obviously someone having no or low weight bearing on one and no restrictions on the other has significant differences, but mine, although there, were not significant and overall the recovery time was the same.
