The paper is devoted to relations between topological and metric properties of germs of real surfaces, obtained by analytic maps from R2 to R4. We show that for a big class of such surfaces, the normal embedding property implies the triviality of the knot, presenting the link of the surfaces. We also present some criteria of normal embedding in terms of the polar curves.
