A system is provided for reconstructing the natural torque between the natural knee and the natural hip area, including a saw jig (2) with an exact parallelepipedal configuration, traversed by saw slots (16, 17, 18) for producing perpendicular ventral and dorsal and diagonal cuts. The front face of the saw jig can be placed on the horizontal cut of the femur (13) and detachably fixed thereto. The saw jig has a central opening (19) and is provided with coupling means for detachably coupling to a rotational jig (1). The system also includes an intramedullary pin (11), provided on the femur side, which can be connected in a pivoting manner to the rotational jig (1) and can be inserted in the femoral bone canal. The saw jig (2) can be threaded onto the intramedullary pin (11) and can then be coupled to the rotational jig (1), whereby the intramedullary pin (11) forms a pivoting axis for the saw jig (2), about which axis the latter can be pivoted plus or minus 10° about the horizontal. In addition, the system is provided with a drive mechanism (14), which pivots the saw jig (2) about the horizontal.
