  In the late `90s there was a flurry of activity relating $1$-rectifiable
sets, boundedness of singular integral operators, the analytic capacity of a
set, and the integral Menger curvature in the plane. In `99 Leger extended the
results for Menger curvature to $1$-rectifiable sets in higher dimension, as
well as to the codimension one case.
  A decade later, Lerman and Whitehouse, and later Meurer, found
higher-dimensional geometrically motivated generalizations of Menger curvature
that yield results about the uniform rectifiability of measures and the
rectifiability of sets respectively.
  In this paper, we provide an extension of Meurer's work that yields a
characterization of countably $n$-rectifiable measures in terms of
$\sigma$-finiteness of the integral Menger curvature. We also prove that a
finiteness condition on pointwise Menger curvature proves rectifiability of
Radon measures. Finally, motivated by the partial converse of Meurer's work by
Kolasinski we prove that under suitable density assumptions there is a
comparability between pointwise-Menger curvature and the sum over scales of the
centered $\beta$-numbers at a point.
