Zimmer Introduces Comprehensive Range of Trabecular Metal Augment Shapes and Cones for Knee Revision Surgery

WARSAW, Ind., May 17, 2011 /PRNewswire/ –Zimmer Holdings, Inc. (NYSE and SIX:
ZMH), a global leader in musculoskeletal care, today announced the launch of a
new, comprehensive range of Trabecular MetalMaterialaugment 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 MetalTibial 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 TrabecularMetal Technology provides more
normal physiological loading which has the potential to decrease stress
shielding and improve long-term implant fixation.
