I speak not from my personal experience but that of my fiancee. Make sure you look for a surgeon that will do the hip replacement via the anterior approach rather than the posterior approach. My fiancée had the anterior approach (incision made about even with the side seam in your pants just behind the FRONT pocket opening) and she was up & walking 3hrs later with no cane, no walker, just a bit of arm holding from the physical therapist. She even did a couple stairs.
The old school posterior approach cuts into you right around the middle of your BACK pocket, meaning there's a lot of muscle that has to be cut. The surgeon is able to just move muscle aside when using the anterior approach.
Post OP, she never took any pain meds, never used a cane or walker and said she wished she had done the surgery sooner.
Best of luck, I saw the pain she was in & wouldn't wish it on anyone.
