WebThe joint lines in the frontal and sagittal planes have a characteristic or well-defined orientation to the mechanical and anatomic axes. This is defined as Joint Orientation Angles. The name of each angle specifies whether it is measured relative to a mechanical (m) or an anatomic (a) axis. WebJul 1, 2024 · The mechanical axis is a line extending from a point proximally dividing the medial and lateral intercondylar tubercles of the tibial plateau and a point equidistant to the cranial and caudal aspects of the trochlea of the talus. AMA-angle is the angle made between the anatomical axis and the mechanical axis.
