Abstract: A tibial sizing apparatus includes a tibial sizing plate. The tibial sizing plate includes a substantially planar surface and defines a peripherally positioned pin slot extending obliquely relative to the substantially planar surface. An alternative tibial sizing apparatus includes a tibial sizing plate and an angulated handle coupled to the tibial sizing plate. An alternative tibial sizing apparatus includes a tibial sizing plate and a catch member coupled to a peripheral portion of the tibial sizing plate. The catch member is movable between a first position in which the catch member extends generally inferiorly from the tibial sizing plate and a second position in which the catch member retracts generally superiorly into the tibial sizing plate. A method for fixing a tibial sizing plate to a proximal tibia includes anteriorly pinning the tibial sizing plate to the proximal tibia.
