Hi Steven, like many of us, you've taken all sorts of different steps to deal with this and are ready to look at HR as a solution.
You can look through the posts for many different folks here for the aftercare they needed, in particular for folks like Pat who went abroad (for them) for the procedures. I am at 2 years now (in nine days) and can honestly say that I needed no intensive interaction with my surgeon.
I was more involved with my home nurse for the first three weeks, with my home PT for the same time, then with outpatient PT. My surgeon was a phone call away, and I did call, but I think any issues would have been able to be treated by local doctors; I don't really think that in my case I really needed to have my surgeon there. I did have a good recuperation both times and no issues, so I can't talk for people who had a harder time, hopefully they can chime in and give their thoughts.
I did have a good surgeon reasonably nearby (40 minutes to an hour), but I only saw him during the surgery, at six weeks, at six months, at a year and I just saw him today for my two year checkup. So in my case while it's nice, it wasn't really necessary to have him nearby.
The travel I can't speak to outside of my one hour trip home, but others have made both long trips by car or by plane and seem to have done Ok. Whatever choice you make, my only advice would be to find the best doctor possible, with geographical proximity being a distant second in consideration. My doctor had 800 procedures done by the time he did me, did many HRs per week and had a strong staff of nurses, physical and occupational therapists, plus a real commitment to the procedure. The thing you really don't want is a doctor that is lacking in those.
