1. A distal cut guide assembly for cutting a distal end of a femur, the femur having an intramedullary canal defining a canal axis, said distal cut guide assembly comprising:

  • an alignment guide having an upper surface, an opposing lower surface and an elongated slot extending therethrough from said upper surface to said lower surface, said slot defining a slot axis, said slot axis extending at an angle relative to said canal axis;

    a cut guide body having opposing first and second surfaces, opposing distal and proximal sides extending between said first and second surfaces, and opposing anterior and posterior ends extending between both said first and second surfaces and said distal and proximal sides, said cut guide body defining at least one cut guide surface extending from said first surface to said second surface, said distal side having a rail extending between said anterior and posterior ends and defining a rail axis;

    a coupling member having an upper portion and a lower portion, said upper portion slidably received within said slot and having an opening extending therein, said opening in alignment with said slot, said lower portion protruding from said slot and having a channel, said rail of said cut guide body being slidably received within said channel such that said rail axis extends at an angle relative to said slot axis and said canal axis, said upper portion being at least partially rotatable within said slot to thereby adjust the angle of said rail axis relative to said slot axis; and

    a handle having an engagement end extending through said slot and in an adjustable engagement with said opening of said coupling member, said handle adjustable between a locked position wherein said engagement with said opening prevents both said upper portion from sliding and rotating within said slot and said rail from sliding within said channel, and a released position wherein said engagement with said opening allows both said upper portion to slide and rotate within said slot and said rail to slide within said channel.
