The present disclosure relates to an articulated knee for arthroscopy simulation that allows true-to-life training. The articulated knee includes an articulation mechanism provided with a framework for coupling to a simulator, and angular and lateral articulation means, traction means and means for quantifying these movements, as well as means that allow force feedback, not only in the movements achieved along each of the axes of rotation and traction of the knee but also the movements achieved by the rods connected to the haptic devices, which are introduced through the entry portals, simulating the surgical instrument.
