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.

Claims

exact text as granted — not AI-modified

What is claimed is:  
     
         1 . 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.    
     
     
         2 . The modular tibial component for a knee joint prosthesis of  claim 1 , wherein the first generally cylindrical cavity includes a first central axis and the second generally cylindrical cavity includes a second central axis, the first and second central axes being parallel to one another and spaced apart.  
     
     
         3 . 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.
