TOC Physicians Specializing in Joint Replacement
Total Knee Replacement
A knee replacement is recommended for patients with arthritis and certain knee injuries or diseases that have not responded well to conservative treatments such as anti-inflammatory medications or cortisone injections. The replacement devices are designed to relieve pain caused by cartilage damage, and usually last up to 20 years in most patients.
During the knee replacement procedure, the entire joint is replaced with an artificial prosthesis. The end of the femur is replaced with a metal shell, while the end of the tibia is fitted with a plastic cup and metal stem that fit into the shell. The posterior cruciate ligament and kneecap may be replaced if needed or may be left in place. This procedure can take up to three hours to perform and usually provides immediate pain relief and a return to regular activities. Our knee replacement surgeons use computer assisted navigation and robotics which allows for precise cuts and placement of the prosthesis resulting in better outcomes for our patients.
Mako Robotic-arm Assisted Technology For Total Knee Replacement
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.
How Does Mako Technology Work?
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 Total Triathlon 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
Why Choose The Orthopaedic Center For Your Mako Procedure?
It’s important to understand that the surgery is performed by our fellowship-trained orthopedic surgeons, who guide 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.

Partial Knee Replacement
Mako partial knee replacement is a minimally invasive procedure for those suffering with painful early to mid-stage osteoarthritis of the knee. It is performed using the surgeon-controlled robotic arm system and offers more accurate resurfacing of the diseased portion of the knee, saving as much of the original knee as possible.
As a partial knee surgery, Mako surgery can be performed on either the medial (inside) compartment, patellofemoral (top) compartment, or the lateral (outside) portion of the knee. It can also be performed as a bicompartmental procedure on both the medial and patellofemoral portions of the knee. In many cases, patients are permitted to walk soon after surgery, drive a car within two weeks and return to normal daily activities shortly thereafter.
What Can Knee Replacement With Mako Technology Do?
The use of this highly advanced robotic arm technology can:
- Enable surgeons to accurately resurface the arthritic portion of the knee and preserve healthy tissue and bone
- Facilitate optimal implant positioning to result in a more natural feeling knee following surgery
- Result in a more rapid recovery and shorter hospital stay when compared to traditional total knee replacement surgery
- Promote a rapid relief from pain and return to daily activities
The Mako system assists the orthopedic surgeon in several ways. First, it provides patient-specific three dimensional modeling for pre-surgical planning. Then, during the procedure, the combination of the robotic arm and stereo tracking technology provides the surgeon with real-time visual, tactile and auditory feedback, enabling reproducible precision and optimal positioning of the implant(s) within the knee. It is this level of accuracy that facilitates optimal implant positioning and alignment to result in a more natural knee motion following surgery.
Candidates for Knee Replacement With Mako Technology
Although the best treatment for each patient must be determined individually, typical Mako patients share the following characteristics:
- Knee pain with activity, usually on the inner knee, under the kneecap or the outer knee
- Start up knee pain or stiffness when activities are initiated from a sitting position
- Failure to respond to non-surgical treatments or non-steroidal anti-inflammatory medication
Like other knee arthroplasty procedures, Mako is typically covered by most Medicare-approved and private health insurance providers. Please speak with your physician to determine if the Mako system may be the right treatment option for you.
Total Hip Replacement
Hip replacement is usually a last resort treatment for patients with severe hip pain whose daily lives are affected by the pain, including those with arthritis, fractures, bone death or other conditions. In this procedure, the diseased bone and cartilage are replaced with a metal ball and plastic cup.
The artificial joint, called a prosthesis, may be cemented in place, may be cementless, or may be a hybrid of both. The prosthetic devices provide pain relief and restored function for 25 years or longer in most cases.
Most patients who undergo hip surgery achieve successful relief from their condition, including pain relief, restored function and an improvement to their overall quality of life.
Mako Smartrobotics™ for Total Hip Replacement
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 hip 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 hip pain. If you haven’t experienced adequate relief with those treatment options, you may be a candidate for Mako Total Hip replacement, which may provide you with relief from your hip pain.
How Mako Smartrobotics™ Works
Mako SmartRobotics™ is an innovative solution for many suffering from painful arthritis of the 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 total hip 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 to help protect your healthy bone.2
Mako SmartRobotics™ for Total Hip replacement is a surgical procedure 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.
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 hip joint. 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.
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.
Hip 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.
