1. A rotation assembly for connecting to an operating table for the purpose of rotating a patient's leg around its longitudinal axis, wherein the rotation assembly comprises:
an interface for attaching the foot of the patient's leg to the rotation assembly;
a rotor, to which the interface is connected in a torsionally resistant manner and which is operable to rotate the interface and thus the patient's leg about the longitudinal axis;
a stator, on which the rotor is rotatably mounted, such that the rotor can rotate relative to the stator;
a rotary handle for rotating the rotor; and
a locking assembly for blocking the rotation of the rotor relative to the stator,
wherein the rotary handle is mounted on the rotor so as to move the rotor around an axis of rotation, and
wherein the locking assembly is actuated by moving the rotary handle along the axis of rotation of the rotor in an axial direction away from the interface.
