Reproducibility of Methods for Determining the Knee Axes of Rotation

The Quantified Motion Analysis (QMA) has become in recent years a clinical examination whose understanding and improvement are being developed. Based on a threedimensional projection of the body segments, the QMA must define these segments and their means of union, the axes and centres of articular rotation. Two main techniques exist: predictive estimation techniques and functional techniques which use a calibration movement to estimate the axes and centres of rotation. These latter techniques, known as functional, seem to show a superiority in terms of reproducibility of the estimate of the axis of rotation of the knee, but no consensus exists. The same applies to the calibration movements used.
