I've pretty much got no cartilege in the right knee and only a "hair" in the left. Two years ago, I was looking hard at replacement of both with 5 years. Since then, I've taken to regularly hitting the gym, toning some stuff up and dropping some weight. I don't have anywhere near the pain that I had. I've probably still got replacement in my future, but I think it's out to ten years, maybe more.
