I believe the poster was referring to the test by Orthopedic Analyses, LLC in Chicago. See https://www.orthopedicanalysis.com/order-testing-panel, specifically test #2. I have had a TKR and a Revision to the tibial component which showed no cement left on the tibial component. The doc literally lifted the prosthetic out of my leg, no chiseling. Now, 3 years later, I've got a loose prosthesis yet again. We've done blood work, a CT and I'm waiting for my Nuclear Bone Scan. If I show up with a "hot" knee again, we really have to determine why my body keeps "eating" the cement. On the revision surgery, they found a fracture in the tibial plateau on the far right side which they "built up" with cement. Now the bone and cement are gone. I have an empty spot right below the tibial plateau. This is all so scary and when I mention the concept of allergies to bone cement components or even metal parts (I know I am allergic to Nickel) I get the typical answer of "that is almost impossible or I've never heard of that being an issue". However, when I read this forum, it becomes clear to me that for some of us it is an issue. But geez, what is one suppose to do?

I broke my tibea plateau and had my hardware removed. I had it removed 11 months after my fracture because I got an infection in the bone snd the source was the hardware. I have MCAS and have random sensitivity reactions. Before the hardware surgery I did skin allergy testing for ortho hardware and bone cement ingredients. I found out I was allergic to bacitracin and neomycin. They replaced the antibiotic. The reason I had bone cement is because one corner had not healed all the way. I feel that at month 4 my bone has collapsed, there has definitely been a change. More pain and swelling. My Dr. says that it is not likely my bone collapsed. Something is different, it’s my leg and I feel the change.
How did your TKR go?

I am not sure how to navigate through this on my knee.

I also need to get a hip replacement in the next few months on the same leg. I want to be more educated on my options and better understand what questions around bone cement I should ask this surgeon.

Thank you
