There was an error in the paper Concordance and isotopy of metrics of positive scalar curvature, [3], see [4], which damaged the proof of [3, Theorem 2.9], and, consequently, the proof of [3, Theorem A]. In this article we prove Theorem 2.9 from [3], and this completes the proof of [3, Theorem A]. In particular, it implies that for a simply connected manifold $M$ with $\dim M\geq 5$, psc-metrics $g_0$, $g_1$ are psc-isotopic if and only if they are psc-concordant.
