Abstract: We consider the question: ``If the zero-framed surgeries on two oriented knots in $ S^3$ are $ \mathbb{Z}$-homology cobordant, preserving the homology class of the positive meridians, are the knots themselves concordant?'' We show that this question has a negative answer in the smooth category, even for topologically slice knots. To show this we first prove that the zero-framed surgery on $ K$ is $ \mathbb{Z}$-homology cobordant to the zero-framed surgery on many of its winding number one satellites $ P(K)$. Then we prove that in many cases the $ \tau $ and $ s$-invariants of $ K$ and $ P(K)$ differ. Consequently neither $ \tau $ nor $ s$ is an invariant of the smooth homology cobordism class of the zero-framed surgery. We also show that a natural rational version of this question has a negative answer in both the topological and smooth categories by proving similar results for $ K$ and its $ (p,1)$-cables.
