Orthopaedic Center of the Virginias
Adds Computer Assisted Navigation Technology For Total Knee Replacement
- System helps align implant for stability, movement, and longevity.
July 12, 2005 – The Orthopedic Center of the Virginias announced
today that it has installed a Stryker computer assisted navigation
system for total knee replacement surgery that could shorten hospital
stay, lead to fewer post-operative complications, and improve knee
“Total knee replacement is an extremely successful way to treat
patients suffering from severe knee pain,” said Dr. Frederick Morgan
of the Orthopaedic Center. “The new surgical navigation technology
that we have in place greatly enhances our ability to restore range
of knee function and return patients to normal activity.”
The Stryker knee surgery navigation system uses an infrared camera
and markers along with unique instrument tracking software to continually
monitor the position and mechanical alignment of the implant components
relative to the patient’s knee anatomy. Smart wireless instruments
send data pertaining to the knee kinematics (movement) to a computer.
The computer analyzes and displays kinematic data on a computer
monitor in the form of charts and graphs that supply the surgeon
with the optimum angles, lines and measurements needed to align
the prosthetic knee with the patient.
“It gives us computer assistance in the operating room,” said Dr.
Philip Branson. “With it, we can give a patient a new knee that
has the best possible stability and range of motion. In turn, that
results in a knee replacement that will last longer.”
Total knee replacement is usually recommended for patients with
severe knee pain and disability caused by damage to cartilage from
rheumatoid arthritis, osteoarthritis, or trauma. More than 90 percent
of people who undergo total knee replacement experience a dramatic
reduction of knee pain and a significant improvement in the ability
to perform common activities of daily living.
