The Mako Difference

Mako Total Knee can help lead to better outcomes, like less pain1 and shorter recovery times1, compared to manual surgery.

In clinical studies, compared to manual knee replacement surgery, Mako Total Knee:

  • Enabled surgeons to execute their surgical plans more.2,3

  • Protected soft tissue and ligaments from damage.4,6

  • Resulted in lower pain scores among patients surveyed 6 months after surgery than those who received conventional joint replacement.5

  • Resulted in better patient satisfaction scores among patients surveyed 6 months after surgery compared to those who received a conventional joint replacement.5

The journey of Mako Total Knee Replacement (TKA) surgery

Step 1 - Scan

Before surgery, a CT scan of your knee is taken and used to develop a 3D virtual model of your unique joint.

Step 2 - Plan

The second step is patient-specific surgical planning.

Your doctor uses the 3D CT-based model to evaluate your bone structure, disease severity, joint alignment and even the surrounding bone and tissue so that they can determine the desired size, placement and alignment of your implant.

Step 3 - Mako Can

In the operating room, your surgeon guides Mako’s robotic arm to remove arthritic bone and cartilage from the knee.

Mako’s Accustop™ technology creates a virtual boundary that provides tactile resistance to help the surgeon stay within the boundaries defined in your surgical plan.

Throughout the procedure, Mako provides real-time data to your surgeon, allowing them to assess the movement and tension of your joint and adjust your surgical plan if desired.

Is Mako right for me?

Mako Total Knee Arthroplasty is for people who:

  • Experience severe knee pain or stiffness resulting from: noninflammatory degenerative joint disease (including osteoarthritis, traumatic arthritis, or avascular necrosis), rheumatoid arthritis or post-traumatic arthritis.

  • Haven't experienced adequate relief with conservative treatment options, like bracing, medication or joint fluid supplements.

Important information

Knee Replacements

Total knee replacement is intended for use in individuals with joint disease resulting from degenerative, rheumatoid and posttraumatic arthritis, and for moderate deformity of the knee.

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, pain, infection, bone fracture, 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 and/or foreign body 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 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. It is important to closely follow your doctor’s instructions regarding post-surgery activity, treatment and follow-up care. Ask your doctor if the Triathlon knee is right for you.
