Knee replacement failure

Posted by bduffy @bduffy, Sep 8, 2023

I had a bone scan and was wondering the meaning of results below. Also anyone have a familiar situation. Thank you

Reactive uptake was noted secondary to a right total knee arthroplasty

Good afternoon @bduffy, Welcome to our sharing group of caring folks. I have had bone scans but never saw the words "reactive uptake". I looked up the meaning and found this from Alberta Canada, A bone scan is a test that can find damage to the bones, find cancer that has spread to the bones, and watch problems such as infection and trauma to the bones. A bone scan can often find a problem days to months earlier than a regular X-ray test.

During a bone scan, a radioactive substance called a tracer is injected into a vein in your arm. The tracer travels through your bloodstream and into your bones. Then a special camera takes pictures of the tracer in your bones.

Areas that absorb little or no amount of tracer appear as dark or "cold" spots. This could show a lack of blood supply to the bone or certain types of cancer.

Areas of fast bone growth or repair absorb more tracer and show up as bright or "hot" spots in the pictures. Hot spots may point to problems such as arthritis, a tumor, a fracture, or an infection.

Does this give you a bit of a head start? Where are you located?

Thank you Chris for your reply. I'm in Tennessee.

Your information was helpful. I guess the findings is a loosening of my replacement. My knee buckles and at times feels like a pinching is going on. I'm scheduled to see my surgeon Monday.

Thanks Barron

Whew......I am glad you will see your medical professional on Monday. Would it be possible for you to let me know what you learn about your condition? Thanks.

May you be free of suffering and the causes of suffering.

Well, I'm waiting for a call to let me know the surgery date. This will be surgery #6.

Do they say why it is loose? How long since the original replacement? I had a TKR 3 years ago and just had to have a new plastic spacer put in. The old spacer’s plastic was deteriorating. Even though they just replaced the spacer the pain is intense. Given no reason for deteriorating plastic?

My original replacement was August 31st 2021 I had a thicker spacer place August 30th 2020 two. My surgeon said they're could possibly be. And infection in the joint. he's going to have the fluid tested during surgery. If there is infection, I will have a 2 stage surgery. I had a negative bones scan.
