Loose knee implant

Hi, I've had bilateral replacement and also had 2 revisions because of a loose implant, but it was the spacer/liner that they replaced. The right one was refitted three years ago and seven months I had the left one done. They put in twice as thick of a spacer. That helped us to stabilize the knee. still having some issues with soft tissue an recovery because they can't just swap out the part they have to open the whole knee to check the stability where it is implanted in the femur and tibia. Luckily that was solid.

Hello @lmc, I'd like to invite @rennk, @melcpa86, @gardeningranny and @hbaudouin to share their stories with various parts of their knee replacement becoming loose.

@lmc, has a potential revision been discussed with you as a fix? Have any exercises or options been discussed with you by your provider who found the implant to be loose?

I am awaiting the results of an MRI before any decision is made.

My replacement hasn’t been right since day 1. It’s been two years and I’ve had PT, have exercised…specifically to strengthen areas surrounding the knee…and I’ve had multiple surgeons tell me I need to start over. They look at the x-rays and tell me that the alignment looks good but that it’s obviously loose. I just saw a surgeon that says the issue is that the spacer that was put in is too thin which is what is causing it to be loose so they said they can replace that instead of starting over. After two years of pain, I hope he’s right.

Thanks for this response. Three surgeons have said that the alignment looks fine. I know it must be fixed because I don't want to go on feeling miserable. In addition to the pain, the incision is still warm and not completely closed 15 months post surgery.
