Abstract
A tibial sizer, or set of sizers, used to estimate the appropriate size tibial base plate implanted during knee arthroplasty. The preferred embodiment provides a measurement of the amount of exposed bone between a posterior proximal portion of the tibia and a posterior edge of the tibial sizer (which edge will correspond to the posterior edge of the tibial base plate). Preferably, the sizer includes a head and a handle extending outwardly from the head, as well as a channel with a slider configured and arranged to be slidably positioned within the channel. The slider includes markings for indicating the amount of exposed bone between a posterior proximal portion of a tibia and a posterior edge of the head of the sizer. Additional markings are also provided for indicating a suggested size of tibial base plate with respect to the anterior/posterior direction.
