I had a total hip replacement 5 years ago.The shaft is titanium,the ball is ceramic and the socket is polyethylene.
So far,so good. In fact,most of the time I forget I have a replacement.
Six months or so after the hip I had four discs removed and replaced by ceramic coated titanium discs and the whole thing filled with morphogenic surgical protein,which after electro-magnetic field stimulation over a period of time turned into bone.
Voila! No more pain after thirty years of it.My wife says my grumpiness has diminished too.
No squeaks from my body!

INjecting some kind of bioabsorbable neutral lubricant similar to whale oil under floroscopy might work.

Something like that might work. My doc said it only takes lubricant “microns thick” to be effective —

I know an orthopedist that wrote an article 10 years ago that ceramic hips and knees are not any good and should not be used in implants. Maybe he knew what he was talking about...

Glad to hear you're doing so well!

OK, I am not involved in research but common sense says to me if the device is squeaking that means friction and friction causes wear and ultimately device failure and another surgery.....

No squeaks occurred among a control group of 48 patients who received hips made of metal and plastic.Beyond annoyance and embarrassment, many patients and their surgeons fear that the squeaky ceramic hips may signal that the joints are wearing out prematurely. That could force patients to undergo the very operation - a second replacement of the same hip joint - they had hoped to avoid by choosing ceramics.
If the public becomes educated, maybe they will be able to make a more informed choice before surgery...
