depuy rotating platform failure
« on: September 14, 2009, 06:46:38 PM »
I have a failed(top and bottom parts have loosened) depuy rotating platform knee that is only 4 years old. Has anyone else had this and what was the cause of the failure?
thanks

Most all failures are caused by surgeon error, 4 years is a short time.

That being said, my OS told me he's not doing anymore rotating platforms (Zimmer makes them too) because they have too many problems.

What is your next step, revision?

Good luck,

Hollie,
Thank you. Yes, I need a revision, but I need to find out why it failed in the first place before putting the next knee in. I have gone to two experts outside the geographical area of my surgeon, and neither one found any fault with the job of my surgeon.
So, the options are- the metal, the poly, the cement, the design of the platform, infection(none found to date).  There is likely osteolysis(sp?).
thanks

You're doing the right thing, getting more than one second opinion.

So they can't tell from XRays what is wrong?  Don't know what osteolysis is, great that you don't have infection.

I "heard" loosening of cement is common. 

I'll be very interested to hear what the problem turns out to be, please keep posting.

Sorry if they have to open you up again to find out the reason, but I guess to fix it they would have to do that.

Hollie
