摘要：
Endoprosthesis (1) for arthrodesis of the knee joint with a. a part of the femur (2) having a femur connection structure (5) for the fixed connection with the distal end of the femur, b. a part of tibia (3) having a tibia connection structure (6) for the fixed connection with the proximal end of the tibia, c. a coupling section of the femur side (7) configured in the femur part (2), d. a coupling section of the tibia side (8) configured in the tibia part (3), in which the coupling section of the femur side (7) and the coupling section of the tibia side (8) are connected between yes pivotally with respect to one another around a pivot axis of prosthesis, which runs essentially horizontally medially to laterally in the stenting position (1) as a knee replacement and therefore in its corresponding position essentially with the position of the pivot axis of the natural knee, e. at least one interlocking element (15, 16) that can be moved from one side to another between an interlocking position, in which the coupling section of the femur side (7) and the coupling section of the tibia side ( 8) rigidly interlocked with each other in a predetermined pivot position, and a release position, in which a pivot of the femur side coupling section (7) and the coupling side side section is possible tibia (8) relative to each other around a pivot axis of prostheses, f. a clamping and resetting means (22), which forces the interlocking element (15, 16) with a clamping force in the interlocking position and maintains it therein, and g. an unlocking mechanism, by means of which the interlocking element (15, 16) can be moved in the opposite direction to the clamping force from the interlocking position to the releasing position, characterized in that one of the coupling sections, section of Femur side coupling (7) or tibia side coupling section (8), has a hollow cylindrical section (9) closed on both front sides, circular in cross section, which is oriented with its longitudinal axis o
