Thanks for your kind thoughts, Rogue Moon. But I'd have to win the lottery first. In any case, it will be good to find out how biocompatible this material is.

better cartilage and soon

Ann, I hope you do get a better knee joint soon.  This polymer has great potential in medical and mechanical engineering areas.  Having suffered a back surgery to a blown disc, I too, would welcome a full-sized replacement in my vertebrae.  I hope the trials go well with this stuff.  The body likes to attack and dissolve foreign objects (mostly for good reason) so I hope this substance proves to be as compatible as it is durable.

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

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).

"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.

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.

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.

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.

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!!

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?
