Abstract: An instrumentation set for preparing a proximal tibia during a bi-cruciate retaining procedure can include a tibial resection block and a stylus. The tibial resection block can be configured to be fixed to an anterior portion of the proximal tibia. The tibial resection block can define a slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia. The stylus can have a first block attachment feature and a second block attachment feature. The first block attachment feature can be offset from the stylus a first distance. The second block attachment feature can be offset from the stylus a second distance. The first and second block attachment features of the stylus can be selectively and alternatively received by the slot of the tibial resection block to position the stylus at distinct offset locations relative to the slot.
