Hi, welcome to Bonesmart. I had Supartz injections. It was a last ditch effort that provided me no relief whatsoever.
I have met several people who got a great deal of relief from them, though.
One comment from my surgeon, that might or might not apply to you is, some insurance companies want you to try these injections before they approve a knee replacement.
My insurance company did not require that, but just something to think about.
Wishing you pain free knees-Kimberly
