Total hip replacement surgery is a procedure in which a damaged hip joint is removed (both the ball and socket sections of the joint) and replaced with an artificial hip joint due to breakdown of cartilage causing pain.Total hip replacement surgery can now be performed with the assistance of a robotic-arm, which increases precision and accuracy, among other positive benefits.
Utilizing a robotic-arm to assist in surgery results in greater overall accuracy and precision when compared to traditional surgery. This technique reduces the chances of common complications due various factors such unintended shaking of the surgeons hands. Due to the greater accuracy and control, the risk of misalignment, dislocation, and leg length discrepancy of the replacement hip joint is reduced.
-This technique enables the highly accurate positioning of the artificial hip joint, thus reducing complications which may arise from incorrect positioning of the joint, for example, hip joint dislocation.
-Minimally invasive surgery; most patients (about 90%) are able to begin walking with the aid of a supportive device within 24 hours after surgery.
-Small incision, minimal blood loss, and fast rehabilitation times mean that patients are usually able to return home after just 3 days of recovery in the hospital.
-Surgical time is likely to be slightly longer than with traditional joint replacements, exposing patients to theoretically greater risk of infection.
-Any computerised system is only as good as the information that is inputted into it. This includes the quality of the initial CT scans, and the proficiency of the team using the MAKO system. Appropriate training and experience helps the workflow process and optimally the final surgical result achieved.
-This is a new technology for joint replacement implantation and, as such, there is only early evidence to show long-term enhanced implant performance. The actual implants used are already traditionally tried and tested prostheses.
Robotic-arm assisted total hip replacement surgery utilizes a 3D imaging camera and a machine that controls the whole operation while analyzing the results in real time. Pre-surgery, a computer x-ray is carried out on the patient to assist surgeons in making a detailed plan of action. During the surgery, the robotic-arm helps to position the artificial joint in place according to the predetermined plans to ensure a high level of precision.
Mako technology is used to create a detailed 3D anatomical model of the patient’s joint in advance so the surgeon can pre-plan the procedure with complete precision before going into the operating theatre. The technology enables the surgeon to visualise how the implant will fit with the existing joint anatomy and make minor adjustments to ensure the best possible custom fit. It provides much more detail than a conventional X-ray, helping the surgeon to see things that they wouldn’t be able to see normally so they can determine the optimum size, placement and positioning of the implant. Once the precise details have been finalised, the personalised surgical plan is programmed into the robot’s computer navigation systems to prepare for surgery.
The recovery process will be different for each patient. A typical hospital stay after surgery with robotic-arm assisted technology may be a few days to a week after a partial or total knee replacement, or total hip replacement. Some patients will need a longer duration of stay depending on age, gravity of injury and other health factors. For many, getting up and walking and beginning physical therapy exercises will be possible as soon as the day after surgery. Depending on your post-surgical plan, which will be determined by your surgeon, nurse, and physical therapist, you may need to use some assistance devices at home as part of your recovery. Pain management will also be important to ensuring you as comfortable as possible during your recovery process, and your post-op plan may include pain medications. Outpatient physical therapy is typically prescribed to begin one or two weeks out after surgery.
Who is suitable for the procedure?
Suitable candidates include: Those who suffer from severe pain due to a degeneration of their hip joint, or people with arthritic hip joints that restrict them from normal daily activities. Those who have not responded successfully to non-surgical treatments such as weight loss, medication, and physical therapy.
How long does the surgery take?
In most cases, Robotic-Arm Assisted joint replacement surgery takes a little over an hour. NOTE: Individual results vary. Not all patients will have the same post-operative recovery and activity level. See your orthopedic surgeon to discuss your potential benefits and risks.
What is the Lifespan of an Implant?
All implants have a life expectancy that is dependent on several factors, including the patient’s weight, activity level, quality of bone stock, and compliance with physician orders. Proper implant alignment and precise positioning during surgery are also very important factors that can improve the life expectancy of an implant. Robotic-arm assisted surgery can help ensure implants are optimally aligned and positioned to ensure the longest benefit.
