Have you reported this to your surgeon and had it evaluated yet? That’s the first step to eliminating the problem. Sometimes the squeaking goes away by itself over time (that’s more likely when the implant is made of metal).
Squeaks that develop after getting a new hip implant are not uncommon. But everyone shares your reaction to this problem — clearly, it is not acceptable! The cause of the squeak can be multifactorial (meaning multiple causes combined together to create the problem).
The surgeon must re-evaluate the size and type of implant used and alignment obtained during surgery for both components (cup and stem). X-rays can be used to look for an obvious cause of the problem. There could be issues of alignment. Is the cup tilted or angled off a bit? Was the correct-sized femoral head and neck length used for that individual? Or perhaps infection or loosening of the implant is a contributing factor.
Unfortunately, sometimes squeaks generated by a ceramic-on-ceramic implant can’t be identified and never go away. The surgeon ends up removing the ceramic lining inside the metal socket and replacing it with polyethylene (plastic) liner instead. That solution is almost 100 per cent foolproof.
