What Does Mild Knee Pain Even After Knee Replacement Indicate?
Question: I had a knee replacement 14 months ago, I still have significant pain, I had Pt for a total of 16 weeks. My surgeon now wants to aspirate for cultures, cell count and synovosure. I am told they do not use an anesthetic when they insert the needle to obtain the fluid. Why won't they give me a numbing agent?????
Brief Answer:
Because local anaesthetic infiltration is equally painful.
Detailed Answer:
Hi,
Thanks for choosing healthcaremagic for posting your query
I'm Dr. Sudhir Kumar,
I have gone through your question in detail and understand your concern.
Doctor generally doesn't infiltrate local anaesthetic (numbing agents) for small procedures like aspiration because local anaesthetic infiltration to anaesthetise the part is equally or sometimes more painful then procedure itself. Moreover sometimes the doctor could aspirate with a single prick, so why bother to prick twice (once to use numbing agent and then again to aspirate). So that's why so aspirations are done without numbing agents.
You can discuss with your treating Doctor about it.
Hope I have answered your query.
If you have any further query, I would be glad to help you.
If not, you may close the discussion and if possible you may rate the answer for me, so that I get a good feedback.

I am tempted NOT to have the aspiration because of the painful procedure, couldn't they do the bone scan, the blood work, the standing xrays, the CBC, ESR and the creatine protein test and the alignment test AND then if they still suspected a bone infection I would agree to the cell aspiration??? ????
Brief Answer:
This is not so painful. Aspiration is a direct procedure so more specific.

Hi
Welcome back
I have gone through your question in detail and understand your concern.
CBC,ESR and C reactive protein are not specific as they are indirect and indicate infection in body anywhere, means they are not specific for joint infection. But joint aspiration following by cell count,culture and synovosure is direct method and much more specific for peri prosthetic infection. Moreover joint aspiration is not much painful in expert hands. Probably they are suspecting periprosthetic infection that is why they are suggesting aspiration and tests.
You can discuss with your treating Doctor about it.
