osteoarthritis
"I am an active 60 y/o male; have had 2 surgeries to fix meniscus tears on left knee; also arthritic in that knee.  I am 1 week out from 3rd injection.  1st shot was good -no side effects; 2nd shot - some increased swelling and stiffness; 3rd shot ok; one week out and I notice that I am not sore after sitting at my desk for an hour or more. I actually have to start getting used to trusting my knee when I stand up again!  Definitely helped!  I have not given it the acid test as I am a backpacker and I would usually get significant pain after the first couple of miles hiking.  Initial reaction is that my knee is not perfect with 20% of my meniscus left, and I do still have some pain, but the shots DID HELP.  No complaints."
