Abstract
The concept of malalignment in the frontal plane has significance different from that of malalignment in the sagittal plane. The knee does not have functional range of motion in the frontal plane. Therefore, there is no compensatory knee range of motion for MAD. Because the knee moves in the sagittal plane, the sagittal plane alignment of the hip, knee, and ankle changes with normal knee motion and gait. Although static considerations usually suffice in the analysis of frontal plane alignment, dynamic factors must be considered when assessing sagittal plane alignment.
