An instrument set for preparing a proximal tibia during a bi-cruciate retaining procedure, the instrument set comprising: a tibial resection block configured to be fixed to an anterior portion of the proximal tibia, the tibial resection block defining a slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia; and a stylus having a first block attachment feature that is offset from the stylus a first distance, wherein the first block attachment feature of the stylus is selectively received by the slot of the tibial resection block to position the stylus at an offset location relative to the slot; a vertical cut guide having a body, a medial arm and a lateral arm wherein a medial cut slot is defined between the body and the medial arm and a lateral cut slot is defined between the body and the lateral arm, the cut guide further comprising a tongue extending therefrom, the tongue configured to be received by and slidably translate along the slot of the tibial resection block; a tibial resection level guide having a handle end, an attachment portion and an engaging end, wherein the attachment portion is configured to be selectively received by the slot of the tibial resection block to selectively position the engaging end against a distal femoral resection surface; and a tibial template tool having a first template end and a second template end, the first template end having first inner fingers and first outer fingers, the second template end having second inner fingers and second outer fingers, wherein the first inner fingers are spaced a first distance corresponding to a first tibial island and the second inner fingers are spaced a second distance corresponding to a second tibial island; wherein all of the stylus, the vertical cut guide and the tibial resection level guide are selectively and alternatively received by the slot of the tibial resection block. a tibial resection block configured to be fixed to an anterior portion of the proximal tibia, the tibial resection block defining a slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia; and a stylus having a first block attachment feature that is offset from the stylus a first distance, wherein the first block attachment feature of the stylus is selectively received by the slot of the tibial resection block to position the stylus at an offset location relative to the slot; a vertical cut guide having a body, a medial arm and a lateral arm wherein a medial cut slot is defined between the body and the medial arm and a lateral cut slot is defined between the body and the lateral arm, the cut guide further comprising a tongue extending therefrom, the tongue configured to be received by and slidably translate along the slot of the tibial resection block; a tibial resection level guide having a handle end, an attachment portion and an engaging end, wherein the attachment portion is configured to be selectively received by the slot of the tibial resection block to selectively position the engaging end against a distal femoral resection surface; and a tibial template tool having a first template end and a second template end, the first template end having first inner fingers and first outer fingers, the second template end having second inner fingers and second outer fingers, wherein the first inner fingers are spaced a first distance corresponding to a first tibial island and the second inner fingers are spaced a second distance corresponding to a second tibial island; wherein all of the stylus, the vertical cut guide and the tibial resection level guide are selectively and alternatively received by the slot of the tibial resection block. <EOS>
