Hi, I noticed about 2-3 years ago that the bone in my knee, I'm unsure of what the bone is called but on both my knees when I sit down, and basically when I bend my knees that on the outside of both the bone sort of sticks out. I have quite a slim figure but I don't think that is the reason my knees are like this as I have a sister who has slimmer legs than me but she does not have this problem. I'm a bit self conscious about it. It is most probably nothing major but I was just wondering if anybody could shed a bit of light on to why my knees are like this. I have put two links below, if you look closely you can just about see. Sorry for the bad quality.
