Abstract
A modular tibial component for a knee joint prosthesis. The modular tibial component includes a tray, a stem and an adapter assembly. The tray includes a support surface and downwardly extending extension having a generally circular shape. The stem includes a main body portion and an upwardly extending extension. The adapter assembly connects the tray and the stem. The adapter assembly includes a first generally cylindrical cavity receiving the downwardly extending extension of the tray and a second generally cylindrical cavity receiving the upwardly extension of the stem.
Claims3
A modular tibial component for a knee joint prosthesis, the modular tibial component comprising:
- a tray having a support surface and a downwardly extending extension having a generally circular shape;
- a stem having a main body portion and an upwardly extending extension;
- and
- an adapter assembly connecting the tray and the stem, the adapter assembly including a first generally cylindrical cavity receiving the downwardly extending extension of the tray and a second generally cylindrical cavity receiving the upwardly extending extension of the stem.
A modular tibial component for a knee joint prosthesis, the modular tibial component comprising:
- a tray having a support surface and a downwardly extending extension defining a first axis;
- a stem having a main body portion and an upwardly extending extension defining a second axis;
- an adapter assembly connecting the tray and the stem, the adapter assembly including a first cavity receiving the downwardly extending extension of the tray and a second cavity receiving the upwardly extending extension of the stem, the adapter assembly being selectively engageable with the downwardly extending extension to provide a predetermined offset between the first and second axis in any direction in a transverse plane.
