An implantable device for controlling rotational growth is disclosed. The implantable device comprises a first screw and a second screw inserted using minimally invasive surgical procedures and positioned within holes created by guiding members. The first screw is positioned in an metaphyseal section and the second screw is positioned in a epiphyseal section in distal femur. The implantable device comprises a cable drawn through the first screw and the second screw. Further, the implantable device comprises a cotter or a thin screw inserted in the first screw to lock the cable. The implantable device modifies longitudinal growth and generates rotational movement due to torque generation, thereby promoting the rotational growth of the bone.
