They been doin this for a long time (Score 1)

They've been doing this for more than five years. It's called autologous chondracyte implantation (ACI) or Carticel. Basically they harvest a bit of cartilage and grow it in the lab. Then they harvest a piece of periosteum from your shin - this is like the black lining that you see on chicken drumsticks. Then they carve out the bad cartilage and inject the new grown cells an sew or glue in the periosteum to seal. In six months you cant' tell the difference from the old cartilage. Here is the site where they do this. I've seen this procedure live and it is very cool!! http://www.genzymebiosurgery.com/opage.asp?ogroup= 1&olevel=3&opage=47 Dave Fayer
