"... I really don't want to feel anyone yanking at my bones ..."
Hi Fred-
You really have to dial back the drama level...
The anesthesia guys have a jargon all their own. Rest assured that they are not going to inject a bit of novocaine and hand you off to the knife, hammer, and saw team. It doesn't work like that.
First thing after your arrival at the hospital, you will sign the papers and get into your gown. The prep team will give you a pill to "relax" you; the scant water you get will be a welcome taste, but the overall impact is further driness. As I recall, the OR team gives you a quick once-over, and another pill. This one is much stronger, rohypnol-like. Very disorienting. You may be quizzed to see just how coherent you are. Finally, the moment arrives, you are wheeled into surgery and transferred to the table. Sounds nerve-wracking, but you are blissfully detached by the pre-op medication. It is at this juncture that the OR anesthesia regime applies. They might request a countdown from you. But it really does not matter. They are going to totally numb you; there will be no sensation, no sense of time, nothing.
Post-op, the OR team will deliver you to recovery (and move on to the next customer). In the recovery room, you may feel cold and nauseous, but mostly, just exhausted. You will be watched for signs of pain-related distress, and medicated accordingly. Your operated leg will feel very heavy, your opposite-side knee may be sore, and you may have a killer backache.
Or, you might be like most patients: very very tired for a few weeks, and slowly get up to speed until, after a couple of months, you have to think a bit when people ask you what side was operated on. Really, it happens.
So, it's too bad you messed up your hip joint at an early age. There is no justice sometimes; I know the feeling. But you are fortunate indeed to live at a time when expert joint replacement specialists are working at every major medical center. A couple of hours work from those guys, and you will be all fixed up.
Good luck, let us know how it turns out.
