Abstract:
1. 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 cut guide receiving slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia; 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, wherein the tongue is received by and slidably translates in the medial-lateral direction along the cut guide receiving slot of the tibial resection block; and a locking arm rotatably coupled to the cut guide at a location between the medial and lateral cut slots, the locking arm movable between (a) an unlocked position, wherein the tongue of the cut guide is permitted to translate within the cut guide receiving slot of the tibial resection block thereby moving in the medial-lateral direction and changing locations of the medial and lateral cut slots relative to the proximal tibia corresponding to respective locations of the vertical medial and lateral cuts to be prepared forming an anterior cruciate ligament island in the proximal tibia, and (b) a locked position wherein the locking arm engages the tibial resection block and inhibits (i) movement of the tongue along the cut guide receiving slot and (ii) movement of the cut guide relative to the tibial resection block.
