Hi Sansabosa,
I've been on the other side most of the time, but just had a revision after 3 years, so it was a little complicated but nothing like yours. There was a fear of trochanter fracture, but my OS managed to get the hardware out. I'm 3 week post-op and doing well for a revision.
There were a few concerns I had beforehand and results:
Anesthesia type: I wanted an epidural + twilight sleep. My OS wanted GA. I have a history of nausea and vomiting, so I implored him, but I had no nausea at all. Woke up just fine.
Risk of fracture: was told it was likely Dr. would need to saw open femur to get stem out. He removed the stem with a lot of hard work, but no cutting. Think it helped that he scheduled me last so he had time for any difficulties. Hopefully your Dr. does the same.
Anterior Approach is never used for a complex surgery. They can't see the femur well enough. I wouldn't let a surgeon touch me who said he could use the Anterior approach after the number of surgeries you've had.
I don't know how your country is about using narcotics. Have you been using prior to surgery? I did for 6 months because my pain had become so bad. I'm still on enough because of my dependency prior to surgery. It's taking more, but I'll be lowering the dose over the next 3 months. With your surgical history, I'd hope your surgeon would be understanding of potential pain issues.
I don't know if this helps you, but when I woke up, that horrible groin pain that prevented me from feeling comfortably was gone. Yes, there was surgical pain, but a normal life is within reach. We know what to expect with surgery, but when the problem is fixed, it's amazing how much better you feel.
I was nervous, as we all are before surgery. I don't know if anything gets rid of the nerves but to get the surgery over with. The techniques are far better than your last surgery and I hope you'll be pleasantly surprised. I'm sorry I didn't see you earlier.
Good luck. We're all here for you!
