1. A patient-specific cutting assembly, the assembly comprising:

  • a model file including geometrical data of a bone of the patient, of an intramedullary canal of the bone, and a planned orientation of a cutting block;

    a fixing rod adapted to be longitudinally inserted in and extending partially from the intramedullary canal; and

    a patient-specific cutting block connectable to the fixing rod, the patient-specific cutting block including at least;

    a structure having a patient specific geometry corresponding to the model file of the patient, the structure configured to be connected to a portion of the fixing rod projecting from the bone to reach a unique coupling orientation with the structure coupled to the bone when the structure is connected to a portion of the fixing rod; and

    a cutting guide connected to the structure, the cutting guide being in the planned orientation when the structure is connected to the portion of the fixing rod projecting from the bone.
