Why do I have Ankle Pain?
Total ankle replacement surgery (total ankle
arthroplasty) is intended to provide limited mobility of the
ankle, by reducing ankle pain and preserving the
flexion/extension (up and down) movement within the ankle joint.
Zimmer provides a system to replace the articulating surfaces of the
ankle that have been affected by disease or injury. With the
Zimmer® Trabecular Metal™ Total Ankle
replacement system, your surgeon has an option for restoring natural
movement to the ankle joint.
Benefits of the lateral (side) approach to surgery
Unlike other ankle replacement surgery techniques
which use an incision on the front of the ankle, this procedure uses
an incision on the side of the ankle. That is why it is called a
lateral (side) approach. In this approach, the lower portion of the
fibula is surgically moved to the side to perform the procedure and is
later repositioned with a metal plate.
Benefits to this approach to ankle surgery include:
- Less disruption of nerves and soft tissues surrounding the
ankle joint, which may speed up recovery and help restore a
natural walking gait.1
- The “side” view of your
ankle joint during surgery allows your surgeon to see the joint
better and is intended to help position the ankle
replacement implant more precisely.
- If you’ve
already had surgery on your ankle from a previous injury, the
surgeon may be able to use the existing incision on the side of
your ankle instead of having to create a new one.1
Advancements in Ankle Implant Design
For decades, Zimmer has led the way with joint
replacement innovations, and many are reflected in the
Zimmer Trabecular Metal Total Ankle replacement implant:
- The Zimmer implant has a low-profile design that allows
your surgeon to retain more of your natural bone than with many
other implants. This is called bone sparing.1
- Components of the Zimmer implant work together to restore the
natural movement of the ankle joint. This provides for integrated
movement with muscles and tendons to help achieve a normal walking
- The Zimmer Trabecular
Metal Total Ankle replacement system offers a number of
sizing options, giving your surgeon the ability to choose the
closest fit for your ankle anatomy.
- In ankle
replacement surgery, the “bearing” material is the polyethylene
surface that the metal components of the implant move against.
Zimmer has developed a unique material that has shown to be
resistant to wear.1 Prolong ®
Highly Crosslinked Polyethylene has been used for many years in
other joint implants and is intended to provide durability in the
replacement ankle joint.2
advanced implant material, Trabecular Metal Material, is
not a coating but rather an advanced 3-dimensional structure that
closely resembles the porous structure of natural cancellous
