Resumen (ES)
After knee arthroplasty a new axial balance in the
horizontal plane takes place whose calibration is difficult as
much before, as during the surgery and after the same one,
and whose consequences are of great importance to the joint
future. This study takes as rotational reference from the
extremity, the march angle, which constitutes the global sum
of the rotation angles of the bony elements and joints of the
member, analyzing its evolution during the first year after the
surgery. It could be observed that this angle did not vary after
the surgery in the operated member nor in the control, maintaining
the value of the gonarthrosis and within the rank of
normality, demonstrates the reliability of the present surgical
technique in the location of the implants for the axial balance,
not only in the coronal plane, but also in the horizontal plane,
where the anatomical references and the habitual clinical
and radiological measures are less accurate.
