The cartilage on my femur got pretty mangled when I injured my knee last fall, and I got the doctor to give me the pictures he took when he operated on it. I used these pictures to make a plush version of my femur, complete with fuzzy cartilage flap. Don’t click through if images from the inside of my knee might bother you.
