Hi, and thank you for coming here with your question.
It is not possible to get arthritis in a replacement hip - because both sides of the hip are metal.
It is, however, possible for the area to become weaker and for the replacement parts to shift slightly - either all the time - or more likely when you walk.
Also, if there is any infection that travels through your body, any foreign object (thing that is in your body that didn't grow there naturally) can be a nidus for infection.
Meaning, if there was some bacteria in your body it could have attached itself to the parts of the hip replacement and you can have an infection at that spot.
Both of these scenarios should be able to be seen on x-ray
I should add that artificial hips (as well as other things) these days are created and treated in a way that makes it much more unlikely for that to be the nidus for infection.
Does this help?
Do you have any further questions?
