I was about 5 to 6 hours away. I did the 2 week post-op (suture removal) visit by train and taxi, and then 4 week by driving myself, and then other visits (like the one year) I made a vacation out it. I decided that I would plan to make all of the visits becasue I was the one who chose to see this surgeon. Some folks ask "why drive all the way to Seattle, when you can x-rays right here?" Because I want to ask the doc detailed questions about HR. Other than post-op visits, getting home from surgery can be a little difficult. I'd consider trying to get in and out your vehicle with out the sue of your leg, try it a few times before you go in for surgery. Also, you should prep the vehicle for begin able to lean back and put your feet up a little. Pillows and ice will be your friends on the ride home.
Arranging PT shouldn't be too hard if you have a PT locally. Look for one that has some experience with HR or THR and the posterier surgical approach if that's the route your surgeons uses, probably is. The surgeon can write a script and fax to the local PT, or yo ucan walk out of the hosptial with a script. My PT checked in with the surgeon before we began.
Loose clothes (PJs, sweats) for the ride home. You'll have a lot of swelling, but it generally doesn't move down your leg until a couple days out.
Spouse might be able to stay in the room with you. If not, they might just want to get a hotel. It will be a little busy in your room the first night, checking on vitals, swapping out fluids, emptying the cathetor bag, giving meds,... You'll be out in a 1.5 or 2 days. They start to reduce the busy-ness the second night.
Good luck.
