Carol, He got a little technical at that point but he did mention that there is some looseness on the left side of the knee, and hopefully, if I can build up my thigh muscle it will fill in the looseness. In the meantime it's been a lovely day, exercised, rested, iced etc , then went shopping with my husband, and definitely not thinking about the what if's. As the trite saying goes, it will be what it is, and I did find out that my OS also regularly does revisions, and is one of the best in Houston. I'm just happy to know that the problem has been identified, and that we'll just do what's necessary as time goes along. Meanwhile, after all of the struggles and physical problems of the last two years, I intend to enjoy every day as much as possible. XXDorothy
