Are advanced three-dimensional imaging studies always needed to measure the coronal knee alignment of the lower extremity?

ConclusionsOrthopaedic surgeons should assess lower extremity alignment in standing position, with enough exposure of the extremity to find severe alignment or rotational deformities, and consider advanced 3D images of those patients who have them. Otherwise, HKA angle can be measured with good accuracy with 2D techniques.Level of EvidenceLevel-III diagnostic.
