Tendinosis & New Injury Treatments

There’s a pretty extensive article discussing platelet therapy and prolotherapy here. ( http://thefitnessadviser.com/2009/06/new-medical-advancement-means-no-surgery/ )

I know a lot of you have had tendinosis and other kinds of tendon/ligament injuries, and wonder if any of you all tried these treatments out and what you think about them? Was your experience good/bad and would you recommend it to others?

Thanks in advance,

EDIT: This was meant to be in the injury section.

I know Joe DeFranco was experimenting with prolotherapy on his spinal disc issues a while back, not sure how it worked out for him.
