We calculate angle-dependent magnetoresistance oscillations (AMRO) for interlayer transport of cuprate superconductors in the presence of ($\pi,\pi$) order. The order reconstructs the Fermi surface, creating magnetic breakdown junctions; we show how such magnetic breakdown effects can be incorporated into calculations of interlayer conductivity for this system. We successfully fit experimental data with our model, and these fits suggest a connection between ($\pi,\pi$) order and the anisotropic scattering observed in overdoped cuprates. This work paves the way for the use of AMRO as a tool to distinguish different kinds of ordered states.
