I don't have bad knees, but I just read about this in a WaPo article and thought it might be of interest. I'd "share" the article but since they now require you to sign in for "free" articles, I won't post a link. But here are some excerpts.
Many Americans...deal with chronic knee pain. The culprit nearly always is injured cartilage...
One new solution (rather than replacement surgery) is to "re-grow" cartilage, but the operation is expensive ($40k) and sometimes doesn't take, which is what happened to one patient in the WaPo article, who opted for a new coral-based treatment.
It's called Agili-C, approved in 2022 by the U.S. Food and Drug Administration and developed by CartiHeal, an Israeli company. It is made from a calcium carbonate derived from the exoskeletons of coral that acts as a scaffold in the body to help regenerate bone and tissue...
The coral plug... took a little more than an hour to put in and cost her $200 out of pocket (insurance covered the rest). Over time, the coral will be fully absorbed by her bone, and in its place will be a gooey substance composed of stem cells from her femur bone that acts similarly to natural cartilage. Full recovery is supposed to take two years, but [neo-natal nurse] McHatton says she’s already back to bike-riding, hiking and 12-hour shifts at the hospital...

[Another is] the MISHA Knee System. It was cleared by the FDA last year and used on a 54 y.o. firefighter in CA, who has undergone 12 knee surgeries since 1987: seven on the right knee, and five on the left. Composed of metal and plastic, it looks like a shock absorber in a car and operates similarly, working to take pressure off the knee joint with each step.
It worked so well for him that he opted to have the same device installed on his left knee in April. And now he’s back in the forest.
It cost him about $1,300 out of pocket. Composed of metal and plastic, it looks like a shock absorber in a car and operates similarly, working to take pressure off the knee joint with each step. In December, he had it implanted on the inside of his right knee...
The surgeon in both cases was Cassandra Lee, chief of the division of sports medicine at UC Davis Medical Center, so a search with her name may bring up other articles.It worked so well for him that he opted to have the same device installed on his left knee in April. And now he’s back in the forest.
