I'm not sure you incurred a karmic debt with a slightly fumbled and distracted greeting.
Better safe than out of balance, I say!
recovery from a total hip replacement is easier than recovery from repairing a torn labrum
I can only speak to the first part in that my 88-y.o. aunt and her 63-y.o. daughter both had super beautifully smooth recoveries from their replacements and are thuh-rilled with the pain-be-gone procedure. Having said that, you are younger than both, and I have no idea how long a hip replacement lasts. I'll be interested to hear what your doctor recommends.
