And here's another question: I never thought about this until I talked with my cousins, two females, both about three years younger than I, and both of whom are facing hip replacement. My cousin Cheryl is an x-ray tech, and she said her doctor told her there was some hereditary anatomical issue with her hip joint. What I know about me, is that when I was a small child, I had to wear a brace on my feet because I was so in-toed. I have continued to be that way, along with a slight tendency towards knock-knees, all of my life. So now I'm wondering whether my femurs were angled inward causing the wearing out of my cartilage and the development of the bone spurs. Anyone know? I've also always had very tight hip/leg muscles without much flexibility and I'm really prone to cramping in my feet. And, I can't bend over and keep my heels on the floor, no matter how much I stretch. I haven't ever been to an orthopedist just because I never really thought about it much, just thought I wasn't very flexible.
