Hi Janet, I'm so sorry you are having this knee problem and hope for some relief for you soon. If you are not going to have that knee replaced for a while I would suggest the synvisc shots. These shot do help many but as you know they are only a temporary fix for the problem and will not change the fact that you will need it replaced eventually. As Molly said, the synvisc is a better way to go than Cortisone as the synvisc doesnt cause added problems with the surrounding connective tissues. Don't worry about the statement of it won't last s long. This is not true and present damage has nothing to do with the duration of the new knee. The main thing is your confidence in your surgeon. Talk to him about all this, write down questions so you can have a list of them with you when you seem him next time and all your questions can be answered.
I had my left knee replaced and I worked in PT for many years so if you have questions feel free to ask away.
Cindy
