A device for aligning and guiding a reciprocatingly movable drill rod for drilling a hole through at least either the tibia or the femur forming a knee joint, the hole being intended to receive one end of an anterior cruciate ligament, which is then attached to the bone. The device includes a first tube-like aligning and guiding element (5) which is intended to be introduced into and aligned in the space between the condyles of the femur over the plateau of the tibia and the ends of which are spaced apart at a distance corresponding to the length of the cruciate ligament, and a second aligning and guiding element (9) which is in line with the first element and located externally of the aforementioned space, and which is located from the first element at a distance which is at least partially bridged by a part of the tibia or femur located adjacent the space. …<??>The drill rod has a flat portion to permit the device to be removed from the rod, while still in the drilled holes, via a slit in the first element. …<??>A mill bit is insertable into said space for detachable connection to a rotatable shank inserted in one of said holes for chamfering the hole mouth edges. |
