Hi
@Kay9 I know you have "extra" on your plate... and some of those issues I can't comment on, having different issues myself... everyone on here seems to have something

but some of the things you are expressing concern about I can relate to and share my experience of. I had Posterior Approach for my THR as my surgeon needed the clear field of view that it affords (which Anterior does not), as glynis says. I was devastated when I found out as I had just got my head around having the THR and thought I could "manage" an Anterior but not Posterior... but in the end you want the best result, if Posterior was going to improve the chances of getting that then Posterior was the approach I was going with.... and as it happens, it was fine, didn't even have to "perch" as the wound is more to the side of the butt than on the sitty down bit

I had GA because the anesthetist at the pre op appointment would only say I "
probably wouldn't hear anything" or at least "
probably wouldn't remember it" and the hearing thing freaked me out. The anesthetist on the day of surgery was much more empathetic and said he thought GA was the way for me to go only as I was so strung out about the spinal/sedation route and I would not be as relaxed as they'd like with spinal... ironically if he'd done the pre op assessment I think i would have been able to go with the spinal and sedation, because he said he could have me sedated enough that I wouldn't hear anything... but by then I'd had two weeks to work myself up into a lather about the "probably" part.
You do HAVE to have sedation with it or you will be wide awake, if you have light sedation you may be able to hear, but if you ask for heavier sedation... tell them, and make it CLEAR that you don't want to hear anything... you should be fine. Sedation means you are asleep but still breathing for yourself, essentially with GA your breathing is "taken over" for you for the duration of the op. I had an excellent experience with GA though, so if that's the way you want to go (it is your right to choose) or end up going due to factors beyond your control you'll be fine with that too - there are risks with GA, different than the risks of spinal/sedation but there are benefits too (my legs weren't numb at all, I was up on two crutches within an hour or so of returning to my room post op) modern GA is so much more 'user friendly' than it used to be
I know exactly what you mean about overthinking it all.... it's so very draining. You think, talk, and plan about that hip for months. The waiting is the hardest part of the whole process, by far. Recovery is so much better... there are many more things within your control, and you are so much more able post op, from very early on, than you can even contemplate pre op. My head was full of "what ifs" and "I won't be able to's" - as soon as I'd had the surgery (I mean from five minutes after getting back to my room!) it was more... "okay, what can I do to help myself recover", and the answers were positive; there
were things I could do! Most of the what ifs didn't eventuate and the I won't be able to's were more "I can do if I think about
how to's" It just felt so much better, not feeling like "stuff" was happening TO me
Bye for now
