1. A system for a knee arthroplasty, the system comprising:
a tibial tray having a perimeter wall defining an insert-receiving space, the perimeter wall defining a pair of posterior notches and a single anterior notch; and
an inserter having a main body with a pair of fixed posterior tabs, a moveable anterior tab body having an anterior tab, and a rotatable shaft for controlling movement of the anterior tab body, wherein the posterior tabs are receivable in the posterior notches of the tibial tray and the anterior tab is receivable in the anterior notch of the tibial tray when the shaft is rotated and the anterior tab body is translated into an expanded position
wherein the main body of the inserter includes a foot with a neck protruding upwardly and an arm protruding anteriorly, wherein the foot is bifurcated by a keyway, and the anterior tab body is receivable in the keyway
wherein the anterior tab body includes a pair of keyway wings projecting outwardly in opposite directions, wherein the keyway defines recesses configured to receive the respective keyway wings, thereby preventing anterior-posterior angulation while expansion occurs.
