Polyurethane foam injections or scaffold injections for knees?

Hello @nowforyou, Thanks for helping your friend. I have bone on bone in my left but so far I don't have any pain with it. My right knee is another story having torn the meniscus in my forties and had several steroid shots but no gel shots, I finally had a right knee replacement done in my mid 70s. I'm now 82 and still mobile without knee pain but a lot less mobility. I do struggle with walking but can relate to my friends that are struggling with knee pain. Before my knee replacement I looked into gel injections but my surgeon didn't think it was any better than a steroid shot so my only option was the replacement.
There seems to be a lot of research on your question but I don't think there are any doctors using polyurethane foam injections, or polyurethane scaffold injections. I think if there were, her age would also come into play in trying to get the procedure done. Hopefully you will get other responses if someone has more information on the procedure. Here's what I found using Google Scholar (https://scholar.google.com/):

Hi John,
Thanks for the info. This doesn't address the question of polyurethane foam injections. I'm a big believer that when the pain from being bone-on-bone is affecting daily living, it's time for a replacement. A 97 y/o person doesn't have that luxury, and I hope that medical science comes up with something to at least alleviate their pain.
I'm bone-on-bone in my shoulder, but get by with cortisone shots, and customizing my exercises to avoid irritating it. For now, there's no need to replace it.
In 2022 I had both knees replaced with amazing results. Yes I did a lot of hard work before and after surgery, had a great surgeon, and a great personal trainer. I consider myself very fortunate.
As for nowforyou, I wish I had an answer for your friend. Aside from everything you've already been told/suggested, I don't know what else to try. All the best to you and your friend, and I hope you may find an answer from the fine people on this forum.

Hello John, first off thank you so much for your volunteer work and input you give to so many people on this platform.
Thank you also for all of the information and links that you have provided. I will spend some time looking up this information, so far it seems to parallel the information that I researched and found as well.
I'm so glad that you were able to find relief with your knee replacement and still able to get around even though it may not be as far and as often. Wishing you the very best and thanks again for everything you do!
