Jim, I have never had surgery of this nature but I would suggest something for you as it is working great for my wife and I. She has arthuritis in her neck and I have had a level of it in my upper back and knees. A few months ago we started taking a supplement called Guclosamine Chondrotin. While the pain for both of us has not been totally eliminated it has definately helped us both. I am not sure exactly how it works...shes the health "expert" but in addition to having your knee examined which you should do you might want to incorporate this. I was just curious if you have a job where you do alot of bending, crawling, etc.
