The invention relates to medicine, namely to traumatology and orthopedics.The purpose of the utility model: The aim of the proposed device is to simplify the construction of the apparatus by reducing the number of nodes and components, increasing reliability seat fixing and ensuring immediate torque transmission from the motor to the lower extremity by the use of the helical gear.An apparatus for the treatment of arthrosis of large joints of the lower limbs consists of a frame with holes in which the engine is mounted in the housing. Motor in the housing connected to the gear in the housing. Reducer in the housing is connected to a rod with a screw thread. A rod with a screw thread rod is connected movably with a screw thread which is secured to the frame by means of clamps with bearings. Inside the rod with screw thread are fixed sleeve connected to the fingers which are secured to the pedal straps. Attached to the frame bearing socket of which is placed inside the bearing. Located inside the bearing rod with a screw thread. With a frame connected movably with a sliding frame openings. Sliding frames are connected to the seat frame. On the seat frame fixed backrest and headrest. By moving the frame with openings is attached through a chain stopper. With the motor in the housing connected to the wire. With wire connected turns switch, network switch and plug.The technical result of the proposed utility model:- providing passive movement in the knee joints without axial load. This device is intended to increase the power of hyaline cartilage of the knee joint and gonarthrosis patients undergoing surgery, through passive movement without axial load. The design provides a comfortable position of the patient (reclined) in the device. The design does not contain elements that create resistance and forcing the patient to strengthen the load on the knee jointThe apparatus consists of a small number of nodes, which facilitates its fabrication.The information is taken into a
