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
