Robot-assisted Hip Replacement
Degenerative joint disease (DJD), a common cause of hip pain, is a chronic condition hampering the quality of life of affected individuals. There are different types of DJD and the most common ones include osteoarthritis (OA), post-traumatic arthritis, rheumatoid arthritis (RA), avascular necrosis (AVN), and hip dysplasia.
Robotic assisted hip surgery is a novel alternative to the conventional surgical procedures. It employs robotic technology to assist the surgeon during the surgical procedure. Robotic assisted hip surgery is commonly employed for prosthetic implantation in the management of degenerative conditions of the hip. It enhances the accuracy and precision in the alignment and placement of the implant. This procedure may be used for total or partial hip replacement. It is beneficial in patients with pain while bearing weight on the affected joint, pain or stiffness in the hip while walking or performing other activities, and also in patients not responding to a conservative line of management.
Robotic assisted hip surgery utilizes a CT scan of the patient’s hip to generate a 3-D model of their pelvis and femur. This aids the surgeon in planning the surgery. During surgery, the robotic software provides dynamic information for the surgeon to enhance accuracy of the procedure. Such real-time information assists the surgeon in precise placement of the implant, which can be difficult to achieve with traditional surgical techniques.
The benefits of the robotic assisted partial hip surgery include:
- Precise placement of the hip implant with a reduced risk of hip dislocation
- Better safety and reduced risk of injury to adjacent tissues
- Uniformity in leg length
- Increased longevity of the implant
Mako Robotic-Arm Assisted Technology for total hip replacement
We understand that making sure you know what to expect from the 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 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 Technology works
Mako Robotic-Arm Assisted Technology provides you with a personalized surgical plan based on your unique anatomy. First, a CT scan of the diseased joint is taken. This CT scan is uploaded into the Mako System software, where a 3D model of your hip is created. This 3D model is used to pre-plan 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 the robotic-arm within the pre-defined area and the Mako System. The surgeon guides the robotic-arm 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. This helps to provide more accurate placement and alignment of your implant. 1,2
- Mako Robotic-Arm Assisted Total Hip replacement is a surgical procedure intended for patients who suffer from non-inflammatory 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 the surgeon-controlled robotic-arm during the surgery to position the implant in the hip joint. The Mako 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.
Hip joint 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.
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, 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 sensitivity, soft tissue imbalance, osteolysis (localized progressive bone loss), audible sounds during motion, and reaction to particle debris.
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 physician’s instructions regarding post-surgery activity, treatment and follow-up care. Ask your doctor if robotic-arm assisted surgery is right for you.
