Given a knot K in the 3-sphere, one can construct a family of closed 3-manifolds by performing Dehn surgery on K. We discuss recent results addressing the extent to which the diffeomorphism types of these surgery manifolds determine, or fail to determine, the isotopy class of K. This talk is based on joint work with Baker–McCoy, Baker–Motegi, and Piccirillo.
