The theory of how this works is that it is a purified version of microfracture, which is now prevalent (especially among athletes) and accepted. Microfrature works because the stems cells from the bone marrow form new cartilage, which produces hyaline cartilage material, but also lots of stuff you don't want, making the result inferior to pure hyaline cartilage (called fibrocartilage). So in theory, if you remove the crap (isolate the stem cells), you can get a more pure cartilage formation.
It makes sense and Regenerative Sciences is claiming something like an 80% success rate. Microfrature was controversial at its infancy, but the results spoke for themselves and the sports industry took notice and became early adopters. A similar thing is happening now with stem cell therapy as athletes have taken notice (Bartolo Colón, Jarvis Green). I've been watching Regenerative Sciences for 3-4 years looking for the negative reports to come on (fraud, etc) and haven't seen them. Instead I've seen them rise in popularity, branching out and publishing (results as well as safety and complication data). They're claiming very good results and behaving responsibly as far as I can tell.
