OK, I can understand the MRI being misread.

So why do you think there are reports of pain reduction with joint supplementation? One theory of heard is that somehow the supplementation is bring more fluid into the joint and thereby reducing pain, not that it is actually causing any repair to the damaged cartilage. I know that some doctors are injecting HA into knee joints but I don't know how well such treatments have been studied compared to a placebo or just injecting water into the joint.
