An articulated joint for orthopedic orthoses or braces, where the brace comprises rods for the tibia (51) and rods for the femur (52) and an articulated hinge (53) provided with four pivots designed to ensure the necessary mobility obtained by the presence of multiple centres of rotation, and where the articulated hinge (53) comprises two plates (55, 56) reciprocally connected by means of four quadrilaterally positioned hinging means such as rivets (57) or similar, in order to enclose the ends of the rods (51, 52) which face each other, wherein between the ends of the two rods (51, 52) there are spacers or stops (63), and where the outer plate (55) of the articulated hinge (53) presents openings (61, 62) in which are inserted pairs of stops (63) which limit the ROM of the joint.
