  1. Orientation X, Y and Z: orientation vector components describing the orientation of the axis. Interception X, Y and Z: Interception of the axis of rotation with a plane parallel to the YZ plane, passing through the centre of the talus. Scenario 1: Intact; Scenario 2: section of ATFL; Scenario 3: section of ATFL and CFL; Scenario 4: section of ATFL, CFL and PTFL.
