Patent ID: 6896702

Claim:
An improvement for facilitating securement of a selected tibial augment at an augmentation location on a tibial implant component, the tibial implant component having a tibial tray adjacent the augmentation location and a depending structure extending longitudinally from the tibial tray, the tibial tray having a proximal surface and an opposite distal surface, the improvement comprising: an abutment on the depending structure, the abutment extending transversely along the depending structure adjacent the augmentation location; a securing element coupled with the tibial augment for selective rotation about a longitudinal axis of rotation located adjacent the abutment when the tibial augment is placed at the augmentation location and juxtaposed with the tibial tray; and a securing surface on the securing element arranged for longitudinal displacement relative to the abutment upon rotation of the securing element, the longitudinal displacement engaging the securing surface with the abutment to establish a longitudinal securing force between the securing element and the depending structure for urging the tibial augment against the tibial implant component, and thereby secure the tibial augment to the tibial implant component at the augmentation location.
