Self-Healing Gel Could Replace Cartilage

bobj, glad you liked the article. I hope you were doing all that running on earth, not concrete. This technology is very much in its infancy, as are most of the discoveries I write on reported by universities, instead of commercial companies. That said, hydrogels as a class have a history as cartilage replacements already, so the timeline might be shorter than "normal," if there is such a thing. I guess growing up in Silicon Valley makes me appreciative of Heiseneberg. Anyway, I also have hip issues, although so far only in winter.

Thanks, mydesign. Do you know if the magnetic technique works for someone who has almost no cartilage left?

Given that Hydrogels are already being used for cartilage replacement, what would the best case scenario be for getting this new material approved for use?  Would clinical trials first be required?

Charles, they are clamming that more than 90% of cartilages can regenerate through magnetic therapy within 6-9 months. Moreover, they had shown me some of the cases of their old patients. But when I check with other medical professionals, they said, it's a like a form of alternate medicine and so far it's not medically proven. Bit confusing!!

Ann, as of now knee replacement surgery is the only proven and effective treatment for cartilage wear & tear. Ofcource there are some treatments in alternative medicines like Homeopathy, Ayurveda, Magnetic therapy etc. But such treatments are not widely accepted and even not medically proven. They will first do the treatment for pain management and for most of the patients that's enough to get relief.

Mydesign, I looked into various forms of magnetic "healing" back in the 1990s. Some alternative medicine methods actually work, sometimes or even a lot of the time. But so-called magnetic therapy is just a false claim. You're right, surgery is the only proven method of treating cartilage problems. Too bad it's so expensive.

As a person with an ACL replacement (1988)  and subsequent wear damage to the meniscus and surrounding cartilage, I can only hope this material is approved for surgical applications within the next few years.

"You're right, surgery is the only proven method of treating cartilage problems. Too bad it's so expensive."

Ann, in my country knee replace surgeries are cheaper when compare with the magnetic therapy for cartilage regeneration. A complete single knee replacement cost you less than $3000. At the same time for magnetic therapy they are charging $500-600 per sitting and it require minimum of 6-9 sittings.

Mydesign, I knew the cost of surgery is much lower in non-Western countries, but that's hugely less. And the cost for magnetic therapy looks a lot higher than here (at least the last time I checked several years ago).

notarboca, I'd like to see this commercialized ASAP so I can get a new knee that's got a chance of working right.
