Mako Robotic Partial Knee Replacement

Partial knee replacement (PKR) is a surgical procedure that replaces only the damaged part of the knee joint, typically the medial or lateral compartment, with an artificial implant. The procedure is less invasive and has a faster recovery time than total knee replacement (TKR), which replaces the entire knee joint. However, PKR requires a high level of precision, alignment and accuracy to achieve good outcomes, and this is where Mako robotic technology comes in.

Mako robotic technology is a cutting-edge system that allows surgeons to perform more accurate, well-aligned and precise joint replacement surgeries, including PKR. The system uses a robotic arm that is controlled by a computer program, which helps guide the surgeon during the procedure. Mako technology provides real-time data and feedback to the surgeon, allowing them to make more informed decisions and adjustments during the surgery.

The Mako robotic system begins with a pre-operative CT scan of the patient’s knee joint. The CT scan is then uploaded into the Mako software, which creates a 3D model of the patient’s knee joint. This model is used by the surgeon to plan the surgery, including determining the precise location, alignment and size of the implant.

During the surgery, the Mako robotic arm is used to guide the surgeon’s hand and tools with extreme precision. The arm is programmed to stay within a specific area, ensuring that the implant is placed exactly where it should be. The robotic arm also provides feedback to the surgeon in real-time, allowing them to make adjustments as needed.

Mako robotic technology offers several benefits for PKR patients.
What are the benefits of partial knee replacement with Mako robotics?
  1. Increased precision, alignment and accuracy

Mako robotics allows for a higher degree of precision, alignment and accuracy during the surgery. The robotic arm can make more precise cuts and place the implant in the correct position and alignment with greater accuracy. This increased precision can result in a better outcome for the patient, with less pain and a faster recovery time.

 

  1. Less invasive surgery

Partial knee replacement with Mako robotics is a less invasive surgery compared to traditional knee replacement surgery. The smaller incision size means that there is less trauma to the surrounding tissue, resulting in less pain and a quicker recovery time.

 

  1. Customized surgical plan

The Mako robotic system uses a 3D model of the patient’s knee to create a customized surgical plan. This plan takes into account the patient’s unique anatomy, ensuring that the implant is the correct size and placed in the correct position.

 

  1. Quicker recovery time

The smaller incision size and less invasive surgery mean that patients who undergo partial knee replacement with Mako robotics typically have a quicker recovery time. Patients can usually return to their normal activities sooner than those who undergo traditional knee replacement surgery.

 

  1. Long-term benefits

Partial knee replacement with Mako robotics has been shown to provide long-term benefits for patients. Studies have shown that patients who undergo partial knee replacement with Mako robotics experience less pain, have a quicker recovery time, and have better long-term outcomes compared to those who undergo traditional knee replacement surgery.

 

What is the recovery process like?

After surgery, patients typically spend one to two nights in the hospital. During this time, the patient will be monitored for any complications and given pain medication to manage discomfort.

Physical therapy usually begins the day after surgery. The patient will be instructed on exercises to strengthen the knee and improve range of motion. Patients are usually able to walk with the aid of crutches or a walker within a day or two of surgery.

Most patients can return to normal activities within four to six weeks of surgery.

Why is Mako Robotics important in Partial Knee Replacements?

Partial Knee Replacement requires the implant to be placed with utmost alignment and precision. This can be achieved by Mako Robotics. 

One study published in The Journal of Knee Surgery compared the outcomes of PKR surgeries performed with and without Mako robotic technology. The study found that patients who received a PKR with Mako had a lower rate of complications, such as implant loosening or infection, compared to those who received a PKR without Mako. Additionally, patients who received a PKR with Mako had a faster recovery time and were able to return to normal activities sooner than those who received a PKR without Mako.

Another study published in The Journal of Arthroplasty found that Mako technology can improve the accuracy of implant positioning during PKR surgery.

Frequently Asked Questions (FAQs):

1.What is a partial knee replacement?

A partial knee replacement, also known as unicompartmental knee replacement, is a surgical procedure that replaces only the damaged part of the knee joint. Unlike total knee replacement, which replaces the entire knee joint, a partial knee replacement only replaces one of the three compartments of the knee: the medial (inner), lateral (outer), or patellofemoral (front).

This type of surgery is usually recommended for patients who have damage to only one compartment of the knee joint. Patients with arthritis, osteoarthritis, or other degenerative conditions that have caused damage to multiple compartments of the knee may not be suitable candidates for partial knee replacement.

 

2.What is Mako robotics?

Mako robotics is an advanced technology that is used to assist in partial knee replacements. The technology uses a robotic arm that is guided by a computer program to perform the surgery with greater precision and accuracy. The robotic arm is equipped with a cutting tool that is used to remove the damaged part of the knee joint and replace it with an implant.

The Mako robotic system uses a three-dimensional (3D) model of the patient’s knee to create a customized surgical plan. The surgeon uses this plan to guide the robotic arm during the procedure, ensuring that the implant is placed in the correct position.

4.What is the recovery process like?

After surgery, patients typically spend one to two nights in the hospital.

Physical therapy usually begins the day after surgery. The patient will be instructed on exercises to strengthen the knee and improve range of motion. Patients are usually able to walk with the aid of crutches or a walker within a day or two of surgery.

Most patients can return to normal activities within four to six weeks of surgery. 

 

5.Who is an ideal candidate for partial knee replacement?

Young (< 50 years of age) patients suffering from arthritis in only one compartment of the knee are ideal candidates for partial knee replacements.
