St. Joseph Health, Queen of the Valley Medical Center is excited to announce
it has launched a new, innovative robotic option for knee replacement
surgery as part of its orthopedics program. On Tuesday, January 7,
John Diana, M.D., performed the first Mako robotic-arm assisted total knee replacements
at Queen of the Valley.
“At Queen of the Valley, we strive to provide the best experience
possible and we are proud to now offer this advanced, less invasive option
that can provide a higher degree of accuracy to our patients,” said
Larry Coomes, chief executive officer.
Total knee replacements in the US are expected to increase 673 percent by 20304. This new technology can offer knee replacement patients a shorter hospital
stay with better, more predictable outcomes. Patients who need a total
or partial knee replacement due to trauma or any type of arthritis in
the knee joint are candidates for Mako surgery.
Mako surgery, a CT scan of a patient’s knee joint is taken and uploaded into
the Mako System where a virtual 3D model of the patient’s bone anatomy
is created. During the surgery, the 3D model serves as a roadmap that
can be referenced and adjusted if necessary. By controlling the Mako’s
robotic-arm, the surgeon can expertly remove damaged bone and cartilage
within the pre-defined area and align the knee implant and precisely position
it in place.
This robotics technology serves as a guide, ensuring the surgeon’s
arms are in the appropriate plane so that incisions are perfect every
time. According to Dr. Diana, the Mako’s robotic-arm provides a
computer-guided cutting pathway which enhances the surgeon’s precision.
With the human eye, a surgeon can cut to a precision of around 1-2 millimeters;
with the Mako, the surgeon can achieve pinpoint precision (within .1 mm
of the plan).
“The Mako helps the surgeon achieve excellent alignment and balance
which can be assessed through a smaller incision in the knee joint. This
helps ensure the knee functions optimally and can help patients attain
a faster recovery,” said Dr. Diana. “I have noticed that patients
who have robotic-arm assisted surgery have more consistent results at
six weeks after surgery compared to patients who have traditional surgery.”
For patients in need of a partial knee replacement, surgeons can target
only the damaged part of the knee, sparing and protecting the healthy
bone and ligaments surrounding the knee joint. The technology for partial
knee replacement has been available for more than a decade and studies
have shown robotic-arm assisted partial knee replacements are two to three
times more accurate than manual versions of the procedure,,, and reduce the need for a subsequent surgery.
The system was fully funded by donations from Napa community members to
Queen of the Valley Foundation during the
Generous Heart gala which raised more than $1 million on September 21, 2019.
“We are grateful to our community members for their giving. Their
contributions have allowed us to purchase this advanced technology. We
are thrilled to be able to offer robotic-assisted knee replacement surgery
to our patients. This technology will only enhance and expand our medical
staff’s capabilities,” said Elaine John, chief philanthropy
officer, Queen of the Valley Medical Center.

About Queen of the Valley Foundation
Queen of the Valley Foundation was established in 1969 by a group of local
residents who wanted to ensure ongoing, locally managed support for quality
medical care in the Napa community. They knew that a financially healthy
medical center was vital to the future of the place they called home.
Since its inception, the foundation has raised more than $115 million
for St. Joseph Health, Queen of the Valley’s equipment and facilities,
while increasing community awareness of the medical center's needs.
