Jerry,
I have used Synvisc for the last 9 years I receive the injections every 6-8 months. The injections arent fun and there is a bit of pain shortly after the injections but a week after the third injection there is relief. If I start feeling that the synvisc isnt working I get scheduled for injections again. Dont wait because it will take 3 weeks for the shots and another to start feeling better. I have had 12 surgeries on my right knee and 3 on my left so its just a matter of before replacement.
At my age I have opted out of replacement I will see how I feel at 50 laugh
