Innovative robotic technology allows surgeons to personalize total knee,
and total hip replacement procedures to each patient.
St. Joseph Hospital is one of the first hospitals in Orange County to offer
robotic-arm assisted total knee, partial knee and total hip replacements
with Stryker’s Mako System. This highly advanced robotic technology
transforms the way joint replacement surgery is performed, enabling surgeons
to have a more predictable surgical experience with increased accuracy.
“With Mako, we can provide each patient with a personalized surgical
experience based on their specific diagnosis and anatomy,” said
Ayaz Biviji, MD, an orthopedic surgeon on staff at St. Joseph Hospital.
“Using a virtual 3D model, Mako allows surgeons to create each patient’s
surgical plan pre-operatively before entering the operating room. During
surgery, we can validate that plan and make any necessary adjustments
while guiding the robotic-arm to execute that plan. It’s exciting
to be able to offer this transformative technology across the joint replacement
service line to perform total knee, total hip and partial knee replacements.”
The demand for joint replacements is expected to rise in the next decade.
Total knee replacements in the United States are estimated to increase
by 673 percent by 2030, while primary total hip replacements are estimated
to increase by 174 percent. At St. Joseph Hospital, orthopedic surgeons
perform over 800 joint replacements each year.
St. Joseph Hospital first launched the Mako Total Hip and Partial Knee
Systems in 2012, and in September of this year, acquired the Total Knee
replacement application. The first case successfully completed in early October.
“We are proud to be one of the first hospitals in Orange County to
offer this highly advanced robotic technology for those looking to improve
their quality of life,” says Jeremy S. Zoch, PhD, MHA, FACHE, chief
executive of St. Joseph Hospital. “The addition of the Mako total
knee replacement application to our already robust orthopedic service
line further demonstrates our commitment to provide our community with
The Mako Total Knee application is a knee replacement treatment option
designed to relieve the pain caused by joint degeneration due to osteoarthritis.
Through CT-based 3D modeling of bone anatomy, surgeons can use the Mako
System to create a personalized surgical plan and identify the implant
size, orientation and alignment based on each patient’s unique anatomy.
The Mako System also enables surgeons to virtually modify the surgical
plan intra-operatively and assists the surgeon in executing bone resections.
Dr. Duke Hasson, a St. Joseph Hospital orthopedic surgeon who has used
the new Mako robotic technology to perform total knee replacement procedures
at the hospital, is excited to provide this option to his patients.
“I find a lot of value in being able to offer patients a minimally
invasive solution that is customized to their specific anatomy,”
he says. “The more accurately hip and knee implants are placed in
the patient’s body, the more successful they will be and the longer
they will last.”
The Mako Partial Knee application is a treatment option designed to relieve
the pain caused by joint degeneration due to osteoarthritis that has not
yet progressed to all three compartments of the knee. Following the personalized
pre-operative plan, the surgeon guides the robotic-arm during bone preparation
to execute the pre-determined surgical plan and position the implant.
By selectively targeting only the part of the knee damaged by osteoarthritis,
surgeons can resurface the diseased portion of the knee, while helping
to spare the healthy bone and ligaments surrounding the knee joint. Studies
have shown robotic-arm assisted partial knee replacement to be two to
three times more accurate than manual partial knee replacement procedures.
The Mako Total Hip application is a treatment option for adults who suffer
from degenerative joint disease of the hip. During surgery, the surgeon
guides the robotic-arm during bone preparation to prepare the hip socket
and position the implant according to the pre-determined surgical plan.
In cadaveric studies, Mako total hip replacement acetabular cup placement
has been shown to be four times more accurate and reproducible than manual
total hip replacement procedures.
