The Total Condylar 3 (TC3) constrained condylar geometry was developed to allow load sharing between the implant and the deficient soft-tissue attachments. However, many authors have suggested caution in the use of these devices because of the additional stresses imparted to the cement-bone interface1,2. We report on a series of patients who underwent revision total knee replacement with a Total Condylar 3 implant and metaphyseal cementing, or so-called hybrid stem fixation (Figs. 1-A and 1-B).

Sixty-eight knees underwent revision total knee replacement, performed by two surgeons, between 1990 and 1998. Knees with a fully cemented stem or a liner exchange were excluded, and one . . . [Full Text of this Article]
