I am waiting for the day when we hear you say, they have scheduled me for surgery! I went through Hyalgen, , Synvisc, and lots of other "remedies" before getting my knees replaced.Well, just chronicling the journey again. Broke down and got a Synvisc-Oneshot in the left knee today. Had one in my right knee a year and a half ago and it still feels pretty good. Still battling the teeth to get the ok to do the knees. Seems like a vicious cycle.
