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 from an overdoped cuprate using our model, showing that behavior previously attributed to anisotropic scattering in this material may in fact be due to (pi, pi) ordering. This work paves the way for the use of AMRO as a tool to distinguish ordered states that have different ordering wave vectors.
