This answer was rated:

I had a knee replacement Feb. 2012. On Sept 9 I had a bone scan. the results were loosening, infection or trauma. How will I ever know which one it is?

Dr. Bob :

Great question! Well you know it wasn't trauma, right?

Customer:

yes

Customer:

how will I know if it is infection?

Customer:

i get the feeling my OS thinks this is all in my head even though the bone scan says differently

Dr. Bob :

Did they discuss a "white blood cell scan" with you?

Customer:

no

Dr. Bob :

A white blood cell (WBC) scan is an imaging test that uses a radioactive substance (called a tracer) to look for areas of infection or inflammation in the body.

Dr. Bob :

If the hardware is infected it will light up.

Customer:

could they have done that at the time of the bone scan and didn't tell me

Customer:

i saw the scan on the computer screen and my knee was all white

Dr. Bob :

No. This is a separate test using a different tracer.

Dr. Bob :

Typically with infections, however, there are other clues.

Dr. Bob :

Redness, excessive warmth, fever, elevated sed rate, etc.

Customer:

no, there was no other test. there is no redness, knee is warm, no fever, difficulty getting up from seated postion. difficulty doing stairs, pain wakes me up at night

Dr. Bob :

Should be much better than that by now. Did you have a CT scan?

Customer:

what exactly does trauma mean

Customer:

no CT scan either

Customer:

i guess i need to be more agressive in getting answers from OS

Dr. Bob :

Trauma means injury, such as a fall, car accident, etc.

Dr. Bob :

CT scan might reveal a pus pocket in the adjacent soft tissues or a retained surgical clip or fluid that shouldn't be there. It gives a lot of detailed information.

Dr. Bob :

You have a right (even an obligation) to ask a lot of questions and have them answered to the best of your doctors' ability.

Dr. Bob :

But you didn't expect any complications,right?

Customer:

i will talk to my family doctor tomorrow, the OS will not talk to me directly, he will only talk to my GP. No, i did not expect any complications. I have not had one pain free day since the surgery. Thank you for your help, you have answered more questions than my own doctor. I appreciate your help.

Dr. Bob :

You're welcome. I hope all works out for the best. Keep the faith.

Customer:

Thank you.
