Re: low grade fever two weeks after both knees were replaced
I know everyone immediately thinks "infection" but if her knees were infected, she's probably have more symptoms. I am being tested right now for infections on both knees but mine were replaced 11 years ago so it's a possible infection from elsewhere in my body. A post-op infection is far worse and usually rather dramatic when it happens.
But when my knees were replaced, I also ran slight fevers and was told it was probably from bone marrow escaping into the blood stream from the bone being exposed. I was 102 for a couple of days and then that low grade stuff for several days afterward.
Just keep an eye on them. If they start to really hurt or get red and swollen along with the fever, then you need to do something. But just a low grade fever may be from another cause.
