Modular prostheses with microprocessor controlled knee joints (MPK-microprocessor-controlled knee joint) which aredistributed all over the world and in Russia as well, in some European countries and in the USA became the standard ofexoprosthetic devices. MPK-prostheses in comparison with prostheses with mechanical knee joints provide users additionalfeatures, such as: a higher level of safety during stance and swing phase, quick adaptation to the changes of the speedof walking and direction due to several sensors and real time microprocessor control of a hydraulic unit with a frequencyof 50–100 Hz; as well as reduce the patient’s energy consumption during walking, increase the randomly chosen walkingspeed and possible maximum speed, increase the patient’s physical activity by increasing the average of daily coveringwalking distance; help to decrease usage of additional support devices and wheelchairs, restore previous mobility level,make the walk pattern closer to the physiological as it has never been before, and significantly improve the quality of life.The unexpected conclusion that the patient’s age, the cause of amputation (including vascular diseases), the mobility class(activity level), and the level of amputation do not have explanatory power as predictors for using the functional advantagesof MPK – is confidently confirmed by researchers from different countries. Unfortunately, we could not find information orsome analytics about the topic in Russian and therefore, articles of foreign authors were chosen as the sources of information.

Keywords: amputation, lower limbs, rehabilitation, modular prostheses with microprocessor controlled knee joints (MPK-microprocessor-controlled knee joint), electronic knee modules, mobility, safety, quality of life.
