The slide track is curved to approximately one hundred twenty (120) degrees of arc and is arranged to maintain a drill guide slide traveling therealong that includes a drill guide barrel that is fitted to slide therethrough. By adjusting and locking positioning of the reference rod and base leg rod fitted through the slide block, the drill guide barrel will point at a target depression formed in the reference rod, whereby a drill turned through the drill guide barrel will form a passage from any point on the frontal cortex of the distal femur or proximal tibia to the target de…
