Extract
Revision total knee replacement is often complicated by bone loss and
synovitis, which can result in ligamentous laxity and imbalance. 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).
