Minimally Invasive Joint Replacement Surgery in North Texas
We understand that knowing what to expect from your joint replacement experience
is important to you. As you are reading through this material, please
reach out to us to discuss if you have additional questions.
Each patient is unique and can experience joint pain for different reasons.
It’s important to talk to us about the reason for your joint 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 or hip pain. If you
haven’t experienced adequate relief with those treatment options,
you may be a candidate for Mako SmartRobotics™ for Total Knee, Total
Hip, or Partial Knee replacement.
How Mako SmartRobotics™ Works
Mako SmartRobotics™ is an innovative solution for many suffering from painful arthritis of
the knee or hip. Mako uses 3D CT-based planning software so your surgeon can
know more about your anatomy to create a personalized joint replacement surgical
plan. This 3D model is used to preplan and assist your surgeon in performing
your joint replacement procedure.
In the operating room, your surgeon follows your personalized surgical
plan while preparing the bone for the implant. The surgeon guides Mako’s
robotic arm within the predefined area, and Mako’s AccuStop™
technology helps the surgeon stay within the planned boundaries that were
defined when the personalized preoperative plan was created. By guiding
your doctor during surgery, Mako’s AccuStop™ technology allows
your surgeon to cut less by cutting precisely what’s planned1-3 to help protect your healthy bone.4-8
It’s important to understand that the surgery is performed by an
orthopaedic surgeon, who guides Mako’s robotic arm during the surgery
to position the implant in the knee and hip joints. Mako SmartRobotics™
does not perform surgery, make decisions on its own or move without the
surgeon guiding it. Mako SmartRobotics™ also allows your surgeon
to make adjustments to your plan during surgery as needed.
Total Knee Vs. Partial Knee Replacement
Based on the severity of the arthritis in the knee, total or partial knee
replacement may be recommended by a surgeon. Both procedures involve the
orthopaedic surgeon guiding Mako’s robotic arm to remove diseased
bone and cartilage.
Mako SmartRobotics™ for Partial Knee replacement is a treatment option for adults living with early- to midstage osteoarthritis
(OA) that has not yet progressed to all three compartments of the knee.
Depending on where the arthritis affects the knee, patients may have an
implant inserted in any of the following areas:
In a unicondylar knee replacement, only one area (or compartment) of the
joint is replaced.
A patellofemoral knee replacement replaces the kneecap (or patella) and
the grove at the lower end of the thighbone (or femur).
A bicompartmental knee replacement affects two compartments of the knee
– the inside (medial) and knee cap.
In comparison,
Mako SmartRobotics™ for Total Knee replacement is a treatment option for adults living with mid- to late-stage osteoarthritis
of the knee. With a Mako Total Knee replacement, the entire knee joint
is replaced, and the surgeon inserts a 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.9-11
Mako SmartRobotics™ for Total Hip replacement is intended for patients who suffer from noninflammatory or inflammatory
degenerative joint disease (DJD). Some forms of DJD include osteoarthritis
(OA), post-traumatic arthritis, rheumatoid arthritis (RA), avascular necrosis
(AVN) and hip dysplasia.
IMPORTANT INFORMATION
Knee & Hip Replacements
Knee and hip replacement is intended for use in individuals with joint
disease resulting from degenerative and rheumatoid arthritis, avascular
necrosis, fracture of the neck of the femur or functional deformity of the hip.
Knee joint 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.
Joint 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, severe instability of the joint, or excessive body weight.
Like any surgery, joint replacement surgery has serious risks which include,
but are not limited to, pain, infection, bone fracture, change in the
treated leg length (hip), joint stiffness, hip joint fusion, amputation,
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 of the implant include
dislocation, loosening, fracture, nerve damage, heterotopic bone formation
(abnormal bone growth in tissue), wear of the implant, metal and/or foreign
body sensitivity, soft tissue imbalance, osteolysis (localized progressive
bone loss), audible sounds during motion, reaction to particle debris
, and reaction to metal ions (ALTR). Knee and hip 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 appropriate for you.
Individual results vary and not all patients will return to the same activity
level. The lifetime of any joint replacement is limited and depends on
several factors like patient weight and activity level. Your doctor will
counsel you about strategies to potentially prolong the lifetime of the
device, including avoiding high-impact activities, such as running, as
well as maintaining a healthy weight. It is important to closely follow
your doctor’s instructions regarding post-surgery activity, treatment
and follow-up care. Ask your doctor if a joint replacement is right for you.
