Yikes! I have a friend who had a knee replacement sometime in 2023. She recently informed me that “the glue has let go and the knee has to be completely replaced.” And other than going for walks, she’s not really active. I got my knee around the same time, and I’m 1000% more active than she is. So it’s a little concerning to me. However, it sounds like her knee was secured with “bone cement” in a “two-part adhesive, a type of fast-curing polymethylmethacrylate (PMMA).” I’m pretty sure mine was done as a “cementless fixation” process, where the implant is pressed onto the bone, and the bone grows into it. I’m thinking (hoping) this fixation process is more secure. — Dan

Look up the stars rather than be alarmed by an anecdote.

No idea what specific "glue" she's speaking of, whether that exact glue you mention or something related. But if she's fairly sedentary it wouldn't be a surprise to me that the lack of load-bearing activity on that knee would result in leg bones that are less-tough than they ought to be. Perhaps the bone connection to the artificial parts is what "glue" she is speaking of. I'm sure the docs will think all of this through, when they're evaluating.

Bummer, to apparently already have a knee failure two years down the line.

A DEAR Friend had her knee replaced, said it never felt right and always had pain. After less than 2 years of issues she went to another Dr. only to find out she had a big time infection in the knee. Months of antibiotics, then knee came out and a temporary installed PLUS months more of antibiotics and finally another knee. She's back to walking, bicycling, swimming and enjoying life again.

That happened to my sister when she got her artificial hip. She was a lifelong nurse, and a known staph carrier…as many healthcare providers are. As such…surgical team hast to take extra precautions to prevent staph infection at the artificial joints. Nevertheless, she got the infection. Artificial hip had to come out, a temporary spacer put in, and months of battling the staph infection. In her case it took over a year.
