Accurate preoperative assessment including clinical evaluation, standing radiographs, long-leg scanogram, and 2D/3D CT scans are critical for identifying coronal, sagittal, rotational, and multiplanar deformities. Deformity analysis using malalignment tests and marking of the centre of rotation of angulation (CORA) guides surgical planning.
