Mako Robotic Knee St. Louis 

Stop Living with Knee Pain 

Living with chronic or severe knee pain should not mean giving up the things you love. 

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 a Mako Smart RoboticsTM partial or total knee replacement, which may provide you with relief from your knee pain.

Robotic-Arm Assisted Knee Surgery

Technology has come a long way! But don't be mistaken, it’s important to understand that the surgery is performed by orthopedic surgeon, Christopher Palmer, DO, who guides Mako’s robotic arm during the surgery to position the implant in the knee joint. Mako SmartRobotics™ does not perform surgery, make decisions on its own, or move without the surgeon guiding it. Mako SmartRobotics™ also allows Dr. Palmer to make adjustments to your plan during surgery as needed.

Mako SmartRobotics™ for partial and total knee replacement is a treatment option for adults living with early- to mid-stage 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 one of several different parts of the knee.

How Mako SmartRoboticsTM  Works

Mako SmartRobotics™ is an innovative solution for many suffering from painful arthritis of the knee. 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 partial or total knee replacement.

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 planned1,2 to help protect your healthy bone3 and preserve soft tissue4,5

With the robotic-assisted technology of the Mako Knee System at SSM Health St. Clare Hospital, patients suffering from knee pain, stiffness and restricted range of motion can now benefit from state-of-the-art technology that could potentially provide life-changing results.

Specially Trained Orthopedic Surgeons

Christopher Palmer, DO, of Signature Orthopedics in St. Louis, is an orthopedic surgeon specializing in minimally invasive treatments through the use of robotic technology. Dr. Palmer provides each patient with a tailored and personalized approach to knee replacement surgery. 

Mako Total Knee has transformed the way partial and total knee replacements are being performed.

Since 2007, more than 300,000 total procedures, including total knee, partial knee, and total hip replacement have been performed with Mako across 26 countries worldwide.


Partial & Total Knee Replacement

Knee replacement is intended for use in individuals with joint disease resulting from degenerative and rheumatoid arthritis, or avascular necrosis.

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). Hip and 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 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.
