This is the 21st century. There were alot of things about 20th century medicine that need improvement. Just because we haven't done it this way before doesn't mean it's not valid and useful.
What's not valid is using FR as a place to advertise.
Medical doctors and quack dudes on websites are not mutually exclusive.
I checked out the website, am suspicious...there are lots of anectodal reports from patients, but little in the way of science and double blind studies. Also, wording of the site is classic quacking...use a criticism and turn it into an asset. The site says that Prolotherapy is "little known" and presumably therefore not used much. I would say it is little known because it isn't very effective. Inject a local anesthetic into a joint and it sure as heck will feel better for awhile.
This business about "Natural substances" stimulating the immune system to repair damaged tissues is baloney. While the immune response is involved in healing, the healing response of all soft tissue with the exception of brain is identical...scar tissue forms. The website leaves the distinct impression that this therapy somehow causes the injured tissues not to form scar tissue but instead to completely regenerate.
My review: 5 Quacks.
I'll accept that.
However, when a guy starts talking about the "myth" of surgery; and about how of the thousands of people he's seen, fewer than five have been referred for surgery; I begin to sense a doctor who's probably not to be trusted.
If his methods were truly as effective as claimed, you know the pro sports teams would have been all over it by now.
IMHO, this is a guy who has taken a sometimes-valid approach far beyond reasonable bounds, for personal profit.
