Has anyone tried Synvisc?

I had synvic injections about 10 yrs ago. I had significant cartilage damage on the under side of my patella secondary to trama.

I had a serious of 3 injections to no benefit to myself. My pain and symptoms remained the same. Not to discourage you though, always worth a try, some folks have seen benefit. Although there is always risk of infection since it does penetrate the joint space.
