In computer-assisted robotic surgery, a robot acts as an extension of the surgeon’s eyes and hands in a minimally invasive surgery to replace an arthritic knee. The robotics help surgeons operate more effectively through a smaller incision.
Hip Replacement A total hip replacement involves removing the existing arthritis and placing a metal cup in the socket and a metal stem down the femur. There is a plastic, polyethylene, liner that is placed between the metal ball and socket to provide non metal-on-metal weight bearing surfaces.
After a hip replacement patients are generally allowed to bear weight as tolerated. This is an inpatient procedure requiring a minimum of one nights stay in the hospital. Physical therapy works with the patient during their hospital stay and upon return to home or a rehab facility to maximize their hips condition during the recovery phase.
This procedure can be done through an anterior or posterior approach. Robotic guidance may also be used in your hips replacement for component position accuracy. Ask Dr Domb at your visit which approach would work best for you.
Robotic Assistance and Partial Hip Replacement
Mako can be used for Total Hip Replacement (THR), which is a procedure designed for patients who suffer from non-inflammatory or inflammatory degenerative joint disease of the hip.
The Mako technology provides your surgeon with a patient-specific 3-D model to pre-plan your hip replacement. During surgery, your surgeon guides the Stryker robotic-arm based on your patient-specific plan. This helps the surgeon to focus on removal of diseased bone, helping preserve healthy bone, and assists your surgeon in positioning the total hip implant based on your anatomy.
What is MAKOplasty?
MAKOplasty is a robotic arm assisted partial hip resurfacing procedure designed to relieve the pain caused by joint degeneration due to osteoarthritis (OA).

Partial Hip Resurfacing
Hip resurfacing is generally considered to be a good option for younger patients as less bone is resected from the upper end of the thigh bone. However, some surgeons will do this procedure on older patients too if they feel it appropriate.
- More accurate implant positioning, which can result in a more natural feeling after surgery
- Improved safety and reduced risk of injury to adjacent tissues
- The potential for better long-term function
MAKOplasty total hip arthroplasty is designed to achieve a new level of precision using the latest techniques in total hip replacement and is designed to restore mobility and an active lifestyle. If your surgeon determines that you are a good candidate for MAKOplasty total hip arthroplasty, he or she will schedule a computed tomography (CT) scan of your hip one to two weeks prior to your surgery date. This is used to create your unique surgical plan for optimal implant placement.
Your physician should discuss the specific risks associated with MAKOplasty and other treatment options with you. In addition, you should be informed of any pre-operative and post-operative instructions by your surgeon or his or her staff. As a total hip arthroplasty procedure, MAKOplasty is typically covered by insurance.
Total Hip Arthroplasty
What is MAKOplasty® Total Hip Arthroplasty?
MAKOplasty is a robotic arm assisted total hip replacement procedure designed for those suffering with inflammatory or non-inflammatory degenerative hip joint disease (DJD). Using real-time information and images of your hip, your surgeon knows and controls accurate implant placement, which can be difficult to achieve with traditional total hip replacement techniques without a robotic arm.
What is Degenerative Joint Disease (DJD)?
Degenerative joint diseases (DJDs) are chronic conditions often resulting in pain and the loss of an active lifestyle and quality of life. There are different types of DJD that can affect the hip, including:
- Osteoarthritis (OA), in which cartilage wears down over time
- Post-traumatic arthritis, which results from a severe fracture 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 of the hip joint has lost a healthy supply of blood flow causing the bone to die and the femoral head becomes misshaped
- Hip dysplasia, a condition where bones around the hip joint did not form properly, which may cause misalignment of the hip joint
What Causes Degenerative Joint Disease?
The risk of developing symptomatic degenerative joint disease is influenced by multiple factors such as age, gender and inherited traits that can affect the shape and stability of your joints. Other factors can include: • A previous hip injury • Repetitive strain on the hip • Improper joint alignment bull; Being overweight • Exercise or sports-generated stress placed on the hip joint
MAKOplasty Total Hip Arthroplasty Benefits May Include:
- Accurate placement of your hip implant using the surgeon-controlled robotic arm system, 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 and bone abnormally rubbing together – this may improve the lifetime of the implant
