Euflexxa reviews

I was diagnosed with ITBS about 4-5 months ago, after running with knee pain for about 6 weeks. Ever since I've been (more or less) faithfully doing the exercises and stretches my PT told me to do. Recently got better health coverage and since the knee was starting to bother me more, decided to see an orthopedist and after an MRI said I have early OA and chondromalacia, and recommended Euflexxa. I haven't been able to get ahold of him or his assistant to ask questions, so I was hoping some redditors might be able to help. The reviews I've found for Euflexxa seem pretty mixed, mostly favorable on one site but pretty bad on another. My main concern is whether this stuff will actually prevent the damage from getting worse or if it just keeps my knee from hurting. Seems like if the damage continues but I'm not feeling pain, I'm going to be 10X worse off down the road.
So, has anybody here used Euflexxa? Can you tell me anything about it aside from the slightly-biased information I can find on the manufacturers website? I know this is no substitute for advice from a trained medical professional but I just want to hear what others think of the treatment.
