The Hausdorff dimension of sets containing circles in many directions

Let us consider a sphere $S^{n-1}$ of radius $r$ in $\mathbb{R}^n$, where we have fixed poles $N$ and $S$. Suppose that $K$ is a set in $\mathbb{R}^n$ containing a translated copy of each meridian (that is an $S^{n-2}$-sphere) of $S^{n-1}$. Then the Hausdorff dimension of $K$ must be bigger than or equal to $n-1$.
