If you are talking about Synvisc... YES, YES, YES!!!!
My knee was bone to bone and it was a Blessing sent from Heaven!!! My first shots lasted over a year. I called it my Lube Job. But, they do lesson in length of time they last, depending on how many times you get it. Eventually, I did get a full knee replacement.

They are steroid shots in the knees and remove some excess fluid from the hip, now they want to try jell shots to see if it helps my knees are bone on bone!

I have never heard of those and I have a really bad knee

Well I had my shots, so far not much improvement but they said sometimes it can take up to 8weeks to feel an improvement! How did you do on full knee replacement? They really want to do that on my left knee!
Thanks for letting me know!!!

First time hearing anything about it
