PROBLEM TO BE SOLVED: To provide an internal prosthesis for fixing the knee joint which can be stably fixed while the knee is extended, can hold the turning angle while the tibia is folded against the femur and can be adjusted.SOLUTION: A femur member 2 having a femur shaft 5 connected to a distal end of the femur and a tibia member 3 having a tibia shaft 6 connected to a proximal end of the tibia are provided. The femur member 2 is formed with a femur side connection part 7 and the tibia member 3 is formed with a tibia side connection part 8. The connection parts 7, 8 are connected so that they can relatively rotate around a prosthesis pivot. Furthermore, a latch means having a lock position for locking the rotation of the femur member 2 and the tibia member 3 and a release position for enabling the rotation is provided. The latch means can be kept on the lock position with a retention reset means and can be moved from the lock position to the release position with the lock release mechanism against the retention power of the retention reset means.SELECTED DRAWING: Figure 1
