Knee joint prosthesis
First Claim
1. A modular tibial component for a knee joint prosthesis, the modular tibial component comprising:
- a tray having a support surface and a first extension;
a stem having a main body portion and a second extension;
an adapter body connecting the tray and the stem and establishing a relative offset between the first extension of the tray and the second extension of the stem, the adapter body defining a first cavity to receive the first extension of the tray and a second cavity to receive the second extension of the stem, the adapter body further including a sidewall defining an opening; and
a locking mechanism for coupling the tray to the stem, the locking mechanism including a first locking element passing through the opening and coupling the tray and the stem.

Abstract
A modular component for a knee joint prosthesis is disclosed. The modular 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.

11. A modular component for implanting in a portion of an anatomy, comprising:
-
a tray having a support surface and a first extension;
a stem having a body portion and a second extension;
an adapter operable to connect the tray and the stem, the adapter defining an internal cavity having a first portion to receive the first extension and a second position to receive the second extension, a passage defined by an outer wall of the adapter; and
a locking member operable to pass through at least a portion of the passage defined by the adapter to operably interconnect the tray and the stem. - View Dependent Claims (12, 13, 15, 16, 17, 19, 20, 21, 22, 23)

18. A modular component for a joint prosthesis comprising:
-
a joint component;
a stem having an extension;
an adapter defining a first void extending relative to a first axis and a second void extending relative to a second axis;
wherein the first void and the second void are defined by a side wall;
a passage defined by the side wall;
a locking member operable to pass through the passage and relative to the first axis, the second axis, or combinations thereof;
wherein the locking element is operable to engage at least one of the tray, the first extension, or combinations thereof to assist in compressing the tray relative to the stem. - View Dependent Claims (24, 25, 26)
