Mako Robotic-Arm Assisted Knee Replacement Surgery
What is Mako robotic-arm assisted knee replacement surgery?
Mako robotic-arm assisted surgery (knee replacement surgery) is a less invasive procedure that relies on a robust robotic arm to perform the procedure. This innovative system, created by Stryker, uses a three-dimensional knee model to ensure unparalleled precision during the procedure. The high level of accuracy provided by the Mako system allows the surgeon to create precise incisions for the knee implant, giving patients a sense of reassurance about the accuracy of the procedure.
Under the guidance of Dr van Niekerk, this advanced software allows for meticulous pre-planning of knee replacement surgery. The Mako system has been shown to lead to optimal surgical outcomes, significantly reduced pain, and a shorter recovery duration compared to traditional surgery. This means patients can look forward to a more comfortable and quicker recovery, instilling a sense of hope and optimism.
In a majority of clinical studies, the Mako total knee allowed surgeons to execute their surgical plans with precision, safeguard the ligaments and soft tissue from further damage and enable improved patient satisfaction.
What are the indications for robotic total knee replacement?
This surgery is recommended for individuals who require partial or complete total knee replacement due to degenerative knee disease (osteoarthritis) that has not responded to non-surgical treatments.
Osteoarthritis is a progressive degenerative disorder that leads to the loss and breakdown of cartilage in the knee, causing the bones to painfully rub against each other.
How do you perform Mako robotic-arm-assisted knee replacement surgery?
A robotic total knee replacement is carried out very similarly to a traditional knee replacement surgery, except it's performed with the assistance of a hand-held robotic system.
It's important to note that the robotic system does not perform the procedure alone. Instead, it assists the surgeon, who is in control throughout the operation. The procedure is carried out under general anaesthetic, and an incision is made over the knee. The supportive structures of the knee are gently shifted, and the damaged cartilage and bone from the femur and tibia are removed. The robotic arm, guided by three-dimensional visuals from the CT scan, performs a range of tasks, such as preparing the bone, inserting the implant, balancing the prosthetic device, and ensuring the right fit. The system, with the help of optical trackers and a camera, which is safely secured to the patient's leg, helps place the implant accurately during the procedure. Active robotic sensors map the exact location of the knee replacement and assist with highly precise independent resection. As a result, the surgeon can accurately place the prosthetic using the system as a guide. Once the muscles are returned to their position, the incision is sealed, and the operative area is protected with a surgical dressing.
What can I expect in terms of recovery?
Following the procedure, Dr van Niekerk will manage pain by prescribing medication to alleviate discomfort. You will be advised to keep the wound area clean and dry and receive detailed wound care instructions to assist with this.
