From what I was told at the University of Tennessee when I was there getting Teddi's Liver Shunt surgery the doctor told me that because of their size (Teddi is almost 3 lbs) the knee socket is so small that most of them have this...he said there just isn't enough room to hold the bone in. That being said not all of them will get to the point where they have to have surgery. I think it depends on how active they are and their weight etc. that leads to them having to have surgery.
