Cameron Gordon and John Luecke proved that knots are determined by their complements, in the following sense: for smooth knots $K$ and $K' \subset S^3$ whose complements are homeomorphic, there exists a self-homeomorphism of $S^3$ taking $K$ to $K'$. In fact, if this homeomorphism is orientation-preserving, then $K$ and $K'$ will be isotopic. We will examine the proof from their 1989 paper.
