I tried the synvisc---it worked for two days---I then used cortizone injections three times form March to November. It gave me life back (only temporarily) and it allowed me to officiate...but, in the end, I knew wha I had to do---or rather, what had to be done. Others said it to me, and I will repeat it to you: only you will know when it is time to get it done---sleeping, pain, walking, daily life, etc. While I am stiff now from PT and have trouble sleeping at nights (par for the course at my time after surgery) I can see how much better I feel. The longer you wait, the more pain you will be in prior to the surgery. Only you can make that decision.
I had my knees replaced here in Cleveland at Lutheran Medical Center---part of the Cleveland Clinic; it is their joint replacement center. As for pain after surgery, they did an excellent job taking care of that. I was never in any pain due to the cutting and sawing; there was some discomfort from time to time due to the PT.
While I am moving slowly now, I look back where I was on November 8th, and I have seen how far I have come.
