Serious question- is there data available on hip replacement surgery by age and gender?

3. Yeah, there's quite a bit of data out there.

More women get hip (and knee) replacements, but the need is mainly due to arthritis and osteoporosis, the latter of which women are more prone to getting for various reasons. High heels could contribute to hip arthritis, but lots of other things can go into that, as well. That being said, high heels throw one's feet, knees, hips, and back out of whack. Prolonged wearing of them shortens one's calf muscles, if you don't stretch them out regularly. They're not good even for young women, let alone an 80-something.

There's also that "Men don't like to go to the doctor" thing going on here, too. So, it's not necessarily that women need joint replacements more. There's the element of them just being more willing to undergo the surgery.
