What is MAKOplasty® Total Hip Arthroplasty (THA)?
MAKOplasty® THA is a total hip replacement treatment option for patients who are living with degenerative joint disease (DJD). The hip is one of the body’s largest weight-bearing joints. The hip is called a ball-andsocket because the round ball-shaped head of the thighbone (femur) moves inside the cup-shaped hollow socket (acetabulum) of the pelvis. These bones are covered by cartilage, a layer of strong tissue that cushions the bones and allows smooth, easy movement of the joint. DJD can cause loss of cartilage, resulting in bone-on-bone contact that may result in pain, swelling and stiffness.
MAKOplasty® is an innovative breakthrough solution for those suffering from painful DJD of the hip and need a total hip replacement. MAKOplasty®, powered by the RIO® Robotic Arm Interactive Orthopedic System, allows your surgeon to treat specific hip conditions with accuracy and precision.
How does it work?
If your surgeon determines that you are a good candidate for the MAKOplasty® procedure, prior to your surgery date you will have a hip CT scan performed. This is used to create a 3-D model of your hip, pelvis and femur. The surgeon uses the RIO® software with information from the model to plan your surgery based on your unique anatomy. During surgery, the software provides real-time information to optimize implant positioning and alignment, and the robotic arm is used to prepare your socket and guide accurate placements of the implants. This can be difficult to achieve using traditional surgical techniques without the assistance of the robotic system.
How MAKOplasty® can help
In total hip replacement procedures, the accurate placement and alignment of implant components are critical factors. The MAKOplasty® total hip procedure provides a new level of accuracy and precision in total hip replacement. Benefits may include:
- Accurate placement of the hip implant, which can reduce the likelihood of hip dislocation.
- More consistency in leg length, potentially decreasing the need for a shoe lift
- Decreased risk of the implant/implant and bone/implant impingement (abnormally rubbing together), may improve the lifetime of the hip replacement.
Who is a good candidate for the MAKOplasty® total hip procedure?
If you have one or more of the following symptoms, talk to your doctor — you may be a candidate for MAKOplasty®:
- Pain while putting weight on the affected joints.
- Limping to lessen the weight-bearing pressure on the hip.
- Hip pain or stiffness during walking or other impact activities.
- Failure to respond to non-surgical treatments or pain medication for degenerative joint disease (DJD).
What is DJD and what causes it?
Millions of Americans suffer from Degenerative Joint Disease (DJD). DJD can come in many forms. These include, but are not limited to:
- Osteoarthritis (OA), also called “wear and tear arthritis”, in which cartilage wears down over time. It is the most common type of hip arthritis.
- Post-traumatic arthritis, which results from a sever facture or dislocation of the hip.
- Rheumatoid arthritis (RA), an inflammatory arthritis of the joints.
- Avascular necrosis (AVN), a condition where the “ball” or femoral head has lost a healthy supply of blood flow, causing the bone to die and the femoral head to become misshapen.
- Hip dysplasia, a condition in which bones around the hip did not form properly, which may cause misalignment of the hip joint.
The risk of developing symptomatic DJD is influenced by multiple factors such as age, gender, and inherited traits that can affect the shape and stability of your joints. Other factors include:
- A previous hip injury
- Repetitive strain on the hip
- Improper joint alignment
- Being overweight
- Exercise or sports-generated stress placed on the hip joint
How is DJD treated?
For hip pain, non-surgical treatment options are often the first line of defense. This can include resting the hip from overuse, gentle exercise (such as swimming), or over the counter medicines to manage pain. If your symptoms aren’t responding to non-surgical solutions, be sure to speak with your doctor. You may be a candidate for total hip replacement.
What is total hip replacement?
Patients who have DJD may benefit from total hip replacement, also referred to as total hip arthroplasty. This is a surgical procedure in which the arthritic hip joint is replaced by implants, which include:
- A metal cup with a plastic liner, which replaces the socket (acetabulum) in the pelvis.
- A metal femoral steam and head.
The goal of total hip replacement is to increase mobility and ability to perform daily activities.
After undergoing MAKOplasty® total hip replacement, what can I expect?
A typical hospital stay for a total hip replacement is determined by your MAKOplasty® surgeon. Your surgeon will also determine what physical therapy may be prescribed to you.
As a total hip replacement procedure, MAKOplasty® is typically covered by Medicare. Check with your private health insurance to verify coverage.
What is the lifespan of a MAKOplasty® implant?
All implants have a life expectancy that depends on several factors including the patient’s weight, activity level, quality of bone and compliance with physician’s orders.
Proper implant alignment and precise positioning during surgery are also very important factors that can improve the life expectancy of an implant. Through the use of the robotic assisted surgical system, implants can be optimally aligned and positioned to ensure the longest benefit.
