Windyshores, After quickly reading your message this morning and not having enough time to respond anything earlier, it bothered me that I thought I had all the information, but probably did not. I haven't had time to question the radiologist readings. I have had everything thrown at me just in the past few months. Mainly, first I lost my Husband, my hero and partner in everything in December. Now I had to prepare for TKR in a week. This is a huge undertaking for me. I think this will be on my back burner for a little bit, but it will be bothering me until I ask more questions. Here I was so pleased with my results. Darn, but that's life. Thanks for giving me more food for thought. Sheryl
