Computer-Assisted Surgery
Cutting Edge Technology for Joint Replacements (Continued)
Potential Benefits of Computer-Assisted Surgery
There are several potential benefits for
those that have computer-assisted surgery
with their total joint replacement:
- Designed to help your surgeon place joint
replacement implants with precision, which
may increase the life of your replacement1
- Reduces the risk of dislocation and
revision surgery1
- Results in greater stability and range
of motion3,4
- Helps improve the overall function of
your joint replacement4
Computer-assisted surgery may allow for
less-invasive surgical techniques, which
have several other potential advantages,
including:
- Reduced blood loss during surgery, which
lessens the need for a blood transfusion8
- Faster recovery7
- Reduced length of your hospital stay6
- Shorter post-operative physical
rehabilitation7
- Less scarring5,7
What Happens During Surgery?
Stryker Navigation technology uses special
tracking devices, providing your surgeon a
comprehensive understanding of your joint
mechanics in the operating room (OR).
Armed with this information, your surgeon
can make adjustments within a fraction of
a degree, helping to ensure your new joint
has the stability and range of motion
needed for a successful replacement.
Specifically, the technology uses the latest
advancements in science and computer
engineering to make the procedure more
accurate than joint surgery without it. As
the surgeon moves an instrument within
your joint, special infrared trackers calculate
its position and wireless instruments
instantaneously transfer the data to a
computer in the OR. This information is
then displayed on a monitor as an interactive
model of the anatomy or “blueprint” that
supplies the surgeon with all the angles, lines
and measurements of your unique anatomy.
The surgeon will then replace the diseased
bone with new, artificial joint components
often called prostheses or implants. Joint
implants are engineered to replicate a
normal, healthy joint.
With certain techniques, your surgeon may
use pins that hold trackers around the
incision site of your joint. These temporary
placeholders give the computer key
information and may make the surgery even
more exact, but it does mean the possibility
of additional scarring at the pin points.
Emerging technologies and alternative
techniques may reduce the number of
incisions and therefore reduce scarring.
Talk to your doctor about these techniques.
What are the Potential Risks?
The risk factors associated with
conventional total joint replacement
remain. In addition, surgery time may be
extended. Talk to your doctor about the
types of joint surgery appropriate for you
and the risks associated with any surgery.
