Mako Robotic-Arm Assisted Technology for total knee replacement
We understand that making sure you know what to expect from your joint
replacement experience is important to you. As you are reading through
this material, if you have additional questions please reach out to us
to discuss.
Each patient is unique, and can experience joint pain for different reasons.
It’s important to talk to us about the reason for your knee pain
so you can understand the treatment options available to you. Pain from
arthritis and joint degeneration can be constant or come and go, occur
with movement or after a period of rest, or be located in one spot or
many parts of the body. It is common for patients to try medication and
other conservative treatments to treat their knee pain. If you haven’t
experienced adequate relief with those treatment options, you may be a
candidate for Mako Total Knee replacement, which may provide you with
relief from your knee pain.
How Mako Technology works
Mako Robotic-Arm Assisted Total Knee replacement is a treatment option for adults living with mid to late-stage osteoarthritis
(OA) of the knee. Mako provides you with a personalized surgical plan
based on your unique anatomy. First, a CT scan of the diseased knee joint
is taken. This CT scan is uploaded into the Mako System software, where
a 3D model of your knee is created. This 3D model is used to pre-plan
and assist your surgeon in performing your total knee replacement.
In the operating room, your surgeon follows your personalized surgical
plan while preparing the bone for the Triathlon Total Knee implant. With
over a decade of clinical history, Triathlon knee replacements are different
than traditional knee replacements because they are designed to work with
the body to promote natural-like circular motion.1-4
The surgeon guides the robotic-arm to remove diseased bone and cartilage
within the pre-defined area and the Mako System helps the surgeon stay
within the planned boundaries that were defined when the personalized
pre-operative plan was created. In a laboratory study, Mako Technology
demonstrated accurate placement of implants to a personalized surgical plan.5
It’s important to understand that the surgery is performed by an
orthopaedic surgeon, who guides the robotic-arm during the surgery to
position the implant in the knee joint. The robotic-arm does not perform
surgery, make decisions on its own, or move without the surgeon guiding
the robotic-arm. The Mako System also allows your surgeon to make adjustments
to your plan during surgery as needed.
IMPORTANT INFORMATION
Knee replacements
General indications: Total knee replacement is intended for use in individuals
with joint disease resulting from degenerative, rheumatoid and post-traumatic
arthritis, and for moderate deformity of the knee.
Contraindications: Knee replacement surgery is not appropriate for patients
with certain types of infections, any mental or neuromuscular disorder
which would create an unacceptable risk of prosthesis instability, prosthesis
fixation failure or complications in postoperative care, compromised bone
stock, skeletal immaturity, or severe instability of the knee.
As with any surgery, knee replacement surgery has serious risks which include,
but are not limited to, peripheral neuropathies (nerve damage), circulatory
compromise (including deep vein thrombosis (blood clots in the legs)),
genitourinary disorders (including kidney failure), gastrointestinal disorders
(including paralytic ileus (loss of intestinal digestive movement)), vascular
disorders (including thrombus (blood clots), blood loss, or changes in
blood pressure or heart rhythm), bronchopulmonary disorders (including
emboli, stroke or pneumonia), heart attack, and death.
Implant related risks which may lead to a revision include dislocation,
loosening, fracture, nerve damage, heterotopic bone formation (abnormal
bone growth in tissue), wear of the implant, metal sensitivity, soft tissue
imbalance, osteolysis (localized progressive bone loss), and reaction
to particle debris. Knee implants may not provide the same feel or performance
characteristics experienced with a normal healthy joint.
The information presented is for educational purposes only. Speak to your
doctor to decide if joint replacement surgery is right for you. Individual
results vary and not all patients will receive the same postoperative
activity level. The lifetime of a joint replacement is not infinite and
varies with each individual. Your doctor will help counsel you about how
to best maintain your activities in order to potentially prolong the lifetime
of the device. Such strategies include not engaging in high-impact activities,
such as running, as well as maintaining a healthy weight. Ask your doctor
if the Triathlon knee is right for you.
