Zimmer® ® NexGen® Trabecular Metal™ Tibial Tray ® Give bone a solid hold

A New Joint Venture—Trabecular Metal Technology Plus Modularity The Trabecular Metal Tibial Tray unites stable fixation with modular components to meet a growing demand for knees implanted through mini-arthrotomies. With physical and mechanical properties similar to bone, Trabecular Metal Technology achieves stable initial fixation and helps prevent stress shielding and lift-off. The separate articulating surface is available in Prolong® Highly Crosslinked Polyethylene, which substantially increases delamination and wear resistance.1 And the modular components work with the Zimmer® Minimally...

Trabecular Metal Technology enhances key fixation interfaces, with or without bone cement Modular design allows for use of both conventional and Prolong Polyethylene articular surfaces Hexagonal pegs engage the best bone to improve fixation High-Flexion • A locking screw anchors the 17mm flex articulating surfaces to the tibial tray. • Helps restore natural knee kinematics and active flexion up to 155° based on the patient’s willingness and ability to achieve high-flexion. The central boss for a lock down screw, is coated in Trabecular Metal Material to maximize ingrowth potential Trabecular...

Testing Data cantilever fatigue strength tEST The fatigue strength of this device is approximately 25% higher than the design requirement established by the MG II® Precoat Stemmed Tibial Tray which has been in use since 1989. 120% NexGen Stemmed Tibia Plate Natural-Knee® asymmetric base plate NexGen Trabecular Metal Tibial Tray NexGen Four Pegged Tibial Tray Trabecular Metal Monoblock Tibia LOAD SHARING TEST NexGen Trabecular Metal Tibial Tray MG II Precoat Stemmed Tibial Tray Normalized Fatigue Strength Test LIFT-OFF TEST The results showed that the average maximum lift-off for the NexGen Trabecular...
