1. A system of components for a bi-cruciate retaining procedure, the system comprising:
a tibial tray trial having a U-shaped body portion with a lateral side and a medial side, the tibial tray trial configured to receive an island on a proximal tibia to preserve an anterior cruciate ligament of a patient;
a tibial tray trial insert configured to be coupled to the tibial tray trial, the tibial tray trial insert having a U-shaped body portion with a lateral side and a medial side configured to rest on a resected surfaces of the proximal tibia, the tibial tray trial configured to receive the island on the proximal tibia to preserve the anterior cruciate ligament of the patient, the tibial tray trial insert including at least one of a peg and keel configured to insert into one or more prepared recesses in the proximal tibia; and
a lateral tibial bearing trial and a medial tibial bearing trial configured to couple to the tibial tray trial, the lateral tibial bearing trial configured to couple to the lateral side of the tibial tray trial and be disposed lateral of the island when assembled and the medial tibial bearing trial configured to couple to the medial side of the tibial tray trial and be disposed medial of the island when assembled.
