The apparatus for training knee and hip joints of a patient in the post-traumatic or post-operative period makes it possible to perform controllable bending and stretching motions of the leg or with use of a knee-immobilization device. The patient's foot of the injured leg is secured on a foot pedal, and the motions of the foot are used as a motive force to drive a carriage that supports the foot pedal. Ankle pump motions of the foot pedal are transmitted by means of a ratchet mechanism to a drum that is used for winding a cord. One end of the cord is attached to the drum, and another end can be selectively attached either to the rear crossbar or to the knee-immobilizing device. Depending on the position of the free end of the cord, the disconnectable pulley and direction of motion of the carriage, the injured leg can be stretched or bent.
