摘要：
The present invention relates to a knee-ankle femoral prosthesis intended for persons having an amputated lower limb, comprising a femoral segment (1) suitable for being attached to a femoral connector, and a tibial segment (2) articulating with the femoral segment (1) via a joint (3) reproducing the movements of the knee, said tibial segment (2) articulating with a foot (4) via a joint (5) reproducing the movements of the ankle, a first hydraulic cylinder (6), the ends of which are rigidly connected to the femoral segment and tibial segment, respectively, and a second hydraulic cylinder (7), the ends of which are rigidly connected to the tibial segment (2) and the foot (4), respectively, via a connecting rod (8), wherein said prosthesis is characterized in that the chamber of the first hydraulic cylinder (6) is connected to the chamber of the second hydraulic cylinder (7) and in that it comprises means for controlling the first and/or second hydraulic cylinder (6, 7) depending on the walking phase, such as the stance phase or the swing phase, and/or on everyday situations, such as stairways, slopes or a standing position or the like, such that the bending of the knee enables a dorsiflexion of the ankle that is proportional to the movement of the knee during the stance phase, and such that the bending of the knee results in a dorsiflexion of the ankle during the swing phase.La présente invention concerne une prothèse fémorale genou-cheville destinée à des personnes amputées du membre inférieur comportant un segment fémoral (1) apte à être fixé à une connexion fémorale, et un segment tibial (2) articulé au segment fémoral (1) autour d'une articulation (3) reproduisant les mouvements du genou, ledit segment tibial (2) étant articulé à un pied (4) autour d'une articulation (5) reproduisant les mouvements de la cheville, un premier vérin hydraulique (6) dont les extrémités sont respectivement solidaires du segment fémoral et du segment tibial, et un second vérin hydraul
