THIS would be good news. Forget artificial joint, I mean I might do that someday. My right knee is going, my left ankle also. Both are serviceable but I need more downtime to recuperate though.

I'm going to wait as long as I can and see if this stuff works out. Sounds less complicated than full joint replacement. If that doesn't work out, also virtue in putting it off as much as possible as artificial joint tech is evolving. I've heard horror stories about knee and hip replacement, also heard of success stories.

The unparalleled liquid strength of cartilage, which is about 80 percent water, withstands some of the toughest forces on our bodies.
Synthetic materials couldn’t match it—until “Kevlartilage” was developed by researchers at the University of Michigan and Jiangnan University.
“We know that we consist mostly of water—all life does—and yet our bodies have a lot of structural stability,” said Nicholas Kotov, the Joseph B. and Florence V. Cejka Professor of Engineering at U-M, who led the study. “Understanding cartilage is understanding how life forms can combine properties that are sometimes unthinkable together.”
Many people with joint injuries would benefit from a good replacement for cartilage, such as the 850,000 patients in the U.S. who undergo surgeries removing or replacing cartilage in the knee.
While other varieties of synthetic cartilage are already undergoing clinical trials, these materials fall into two camps that choose between cartilage attributes, unable to achieve that unlikely combination of strength and water content.
The other synthetic materials that mimic the physical properties of cartilage don’t contain enough water to transport the nutrients that cells need to thrive, Kotov said.
