Zimmer Holdings, Inc. (NYSE and SIX: ZMH), a global leader in musculoskeletal care, today announced the launch of a new, comprehensive range of Trabecular Metal Material augment shapes and cones for use in knee revision surgeries.
During revision surgeries, surgeons are often faced with a range of small to large cavitary bone defects. The new augments are designed to fill these defects, provide a structural foundation to the existing bone and help support revision knee implants.
Trabecular Metal Tibial and Femoral Cone Augments have the potential to provide reliable structural replacement of bone and stable fixation for femoral and tibial articulating components in even the most challenging knee revision cases. Designed to treat deficiencies in the knee independent of the final implant position, the tapered shape of the augments fits the patient's anatomy without dictating implant alignment. The new augments are designed for use with the NexGen® Knee System.
"The launch of this fully-instrumented range of revision knee cones reinforces Zimmer's commitment to providing surgeons with the most comprehensive array of solutions to confidently approach knee revisions with the NexGen Knee System," said Jeffery A. McCaulley, President, Zimmer Reconstructive. "The broad range of anatomic sizing options now available allows surgeons to more accurately position implants and fill defects in all kinds of knee revision cases."
The augments are constructed from Zimmer's Trabecular Metal material, a highly porous biomaterial that resembles the structure, function and physiology of trabecular bone. No other porous metal material is supported by the amount of peer-reviewed, published clinical data of Trabecular Metal Technology and its history of clinical success in orthopaedic applications. This novel material supports bone formation, enabling biologic fixation and a stiffness similar to cancellous bone. The elasticity of Trabecular Metal Technology provides more normal physiological loading which has the potential to decrease stress shielding and improve long-term implant fixation.
