#$%^&*AU2018204287B220200227.pdf#####ABSTRACT A modular knee prosthesis system includes a femoral component having a stem, a plurality of different sizes of sleeves mountable on the stem, and a plurality of different sizes of augments mountable on the femoral component. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by selecting the size of sleeve that will provide the desired joint line. The different sizes of sleeves have different axial lengths but share a common geometry along a substantial part of their lengths so that the same bone cavity will accept multiple sizes of sleeves. 3714170v11/15 76A 26A 68A50A 49DA 24A 72A -~ F j 56A 4 7A 768 80 22 268 -68B 8 508 68- 2 24B 728- - 68B 24 50 2 50 56B 47B8 -72 76 7 76C 56 26C -680C1 50C 75 1 24C 18 72C1l 49C 10 56C 470 21 12 )¶-014 Fig.1I
