For a solid anchorage, the implant should be fixed in at least two of three zones. Zone 1 is the epiphysis (joint surface), Zone 2 is the metaphysis and Zone 3 is the diaphysis. Most revision knee systems provide 2-zone fixation in Zone 1 and Zone 3. The Endo-Model Knee System provides fixation in Zone 2 as well. It is possible to have fixation in the following zones:
Zone 1 fixation:
The illustration shows fixation with cement. It is also possible to use cement, bone grafts or metal augments in bone defects. In these cases it is necessary to have at least one additional fixation in another zone to gain stability. 1
Zone 2 fixation:
LINK offers TrabecuLink Femoral and Tibial Cones (TiAl6V4). The cones have high primary stability in the meta-physeal region, both for the cone itself and for the tibial component in the cone. This allows good Zone 2 fixation. The metaphyseal fixation between prosthesis and cone is achieved using cement. 1
Zone 3 fixation:
Zone 3 fixation can be achieved with diaphyseal stems. Zone 3 fixation can off-load the metaphysis and reduce risk of implant cement mantle failure. 1
