Abstract:
1. A modular orthopaedic implant system comprising: a distal femoral component having a pair of spaced, curved distal articulating surfaces, a proximal end opposite the distal articulating surfaces, an interior surface defining a tapered bore at the proximal end, the tapered bore being widest at the proximal end and extending distally from the proximal end, and an exterior surface spaced from the distal articulating surfaces, at least a portion of the exterior surface surrounding the tapered bore, the portion of the exterior surface surrounding the tapered bore being asymmetrical in at least one cross-section, the maximum dimension of the distal femoral component in the proximal-distal direction being the distance from the distal articulating surfaces to the proximal end; and a tapered metaphyseal component mountable to the proximal end of the distal femoral component; wherein the tapered metaphyseal component has an outer surface including a plurality of steps, a proximal end and a distal end, the tapered metaphyseal component being widest at its distal end; and wherein the tapered metaphyseal component includes a tapered post sized and shaped to be receivable within the tapered bore of the distal femoral component and to create a frictional lock between the distal femoral component and the tapered metaphyseal component, the tapered post extending outwardly from the distal end of the tapered metaphyseal component and having a central longitudinal axis that extends through the proximal end of the metaphyseal component.
