Hello

The biggest concern is a septic prosthesis.

This is very serious if it is what is happening.

Take her to the ER NOW for evaluation.

She's been in hopital for ten days now

Then what is your question?

Why have you not simply asked what her diagnosis is? After 10 days?

Customer: replied 1 year ago.
They don't know what's wrong with her . The fevers and chills aren't going away
Expert:  DrRussMD replied 1 year ago.

Then they need to consider

infected prosthesis

endocartitis

These are two main possibilities.

Less likely, kidney infection, bone infection, hidden malignancy.....

Ask them about all of these.

What is septic prosthesis?

Please read the answer I just sent you.

It is an infected joint where they did the replacement.

Can endocarditis happen after knee replacement all of a sudden?
Expert:  DrRussMD replied 1 year ago.

It can, and it can present like this, and be missed.

Echo cardiogram would be needed.

Please click a positive.

Then come back as needed.

Expert:  DrRussMD replied 1 year ago.

The post will not let me edit.

I will do that here.

They can also do repeated blood cultures, if they have not.

At least 3 sets.

They can CT her abdomen, brain, or anywhere else if indicated by exam.

A bone scan can show bone infection.

Good luck.
