I don't have any personal experience with knee surgery or replacement, but I do have experience with something else that IMO would be highly beneficial.
There is a very high potential for you to rebuild your knee from the inside out without the need for replacement if you so wished. It will take time to accomplish and some dedication, but it would also halt and reverse the arthritis.
It's so simple that many people will try to discredit it without having any experience with it. But if having healed knees without recurring surgery and knee replacements is something that you desire, then may I suggest you do some research of your own into the subject.
Studying the works of Arnold Ehret, Dr. Robert Morse, and Dr. Douglas Graham will provide the necessary knowledge to get you started. These three are all very similar in what they suggest. IME, following what they teach will bring about the quickest and deepest form of healing. Something that heals even deeper would be, to water fast, but considering the things commonly found on the food shelves I would highly suggest leaving this alone for a while until you've done a lot of cleansing and healing already. There are also different things you could do which would help, such as avoiding certain foods, but if you start doing the research you will find them. :wink:
