Abstract
Methods, techniques and apparatuses are disclosed including exemplary methods of performing a knee arthroplasty of the tibia. One exemplary method can include determining at least a depth of a distal fixation feature of a tibial implant, and forming a metaphyseal recess in a proximal portion of the tibia. The recess can be configured to receive the distal fixation feature therein and can be sized to exceed at least the depth of the distal fixation feature such that when a distal surface of the tibial implant contacts a proximal surface of the proximal portion of the tibia and the distal fixation feature is received in the metaphyseal recess, a gap remains between the distal fixation feature and one or more surfaces that form a portion of the metaphyseal recess.
