Robotic joint replacement: All you need to know


From Siri, Alexa to self-driving cars and self-driving airplanes to satellite maps, the world has seen the beneficial power of technology for the average person.

“The medical sphere has not been left without attention either; what we thought was fiction in stories and films has now become reality. Artificial intelligence and robots help humans do their jobs better. In the field of orthopedic surgery, robotically assisted knee replacement is revolutionizing the way knee replacements are performed. These advanced robots have infiltrated the operating room floor, helping surgeons achieve precision and accuracy during surgery. Today, robotics has become a new tool in hospitals to provide the best possible treatment, ”says Jalandhar Dr. Shubhang Aggarwal, Senior Joint Replacement Surgeon at NHS Hospital. indianexpress.com

What is robotic joint replacement?

Imagine a pilot flying an airplane through thick fog. A few years ago, they only used their senses and imaginations to land a plane safely. But with advances in technology, the same pilot now has high quality satellite guidance; Autopilot mode allows sensors and an algorithm to smoothly guide the aircraft towards a landing. Likewise, things have changed from when the orthopedic surgeon performed conventional surgery, when he relied on the eyeball with his 2D vision to assess deformities and create bone incisions. He can now use high-tech robotics with self-learning AI to create a live 4D map of the joint, seeing the ideal placement of the artificial implant to be placed, and then a robotic instrument removing only the small bone that was needed. to ensure a perfect fit of the implant while preserving the natural bone and ligaments.

The technology has moved from legacy implant positioning techniques, which used long rods drilled into the central canal of the femur (femur) to provide an attachment point for surgical cutting guides, to impartial robotic planning and execution.

The most advanced innovation is the Navio Surgical System, a robotic platform that does not require CT or MRI and creates a real-time image of the limb and deformity, and the surgeon can visualize everything around the knee and plan what it will be like after surgery, even before touching bones.

This robotic system clearly demonstrates excellence in knee replacement surgery. Using the Navio System, the surgeon can understand the unique anatomy of each individual knee, achieve a natural fit of the knee with the hip and ankle, and the ideal size ensures that knee tracking is balanced across the entire range of the artificial implant. movement. The surgeon can now place an implant with sub-millimeter precision that works and feels like your God gave natural knees. Such robot-assisted knee replacement surgery involves little blood loss, much less pain, little tissue penetration, and precise positioning of the implant with long-term results.

After such a procedure, the patient can start walking only 3 hours after the operation and return home within 3 days. For now, with improved anesthesia and rehabilitation techniques, we are aiming for one day discharge! Thus, with the use of robotic knee replacement surgery, the patient’s stay in the hospital is reduced. In Covid, it makes sense to reduce exposure to a minimum.

What are the Benefits of Robot Joint Replacement?

The main reason for developing robotic systems was to improve patient outcomes. Although, thanks to research, we have the best metals and ceramics for hip and knee prosthetics, proper placement of these implants is critical. It has been noticed that when using traditional methods of surgery, there are a number of patients who are unhappy with the result. Through the use of robotic technology with artificial intelligence and purpose and the hope that these procedures will achieve accurate positioning of the implant, and with the natural balance of soft tissue, tracking is improved, thus further increasing the level of satisfaction with the operation.

The Navio system offers two important advantages: First, it helps the surgeon create a highly personalized plan for a particular patient, and it is not exposed to potentially harmful radiation, unlike earlier computed tomography methods. The second benefit is robotic assistance, which combines advanced technologies to provide perfect, accurate placement of the artificial knee and aim for better long-term results over 30-40 years at a much lower cost.

Over the past couple of years, research has focused on high precision robotic knee replacement systems. A study by orthopedic surgeon Jeffrey Westrich and colleagues published in Knee Surgery Journal found that a robotic system improves accuracy and precision and is useful in training orthopedic surgeons. Another study by researchers from the United Kingdom, published in the Bone & Joint Journal in 2018, found that robotic total knee replacement was associated with shorter hospital stays, less pain after surgery, and improved early functional recovery.

In addition to precision, robotic procedures also provide better protection for the surrounding soft tissue at the surgical site and help maintain healthier bones. During surgery, the implant or components that replace old joints are usually made of metal, ceramic, or plastic. Robotic assistance allows the surgeon to place the implant more efficiently. Robotic surgery leaves much smaller and less invasive scars compared to traditional surgery.

Paving the way for the future

The introduction of robotics has improved the way surgery is performed, including joint replacement. As technology advances, more and more people are demanding the kind of precision that robotics can provide in hip and knee replacement surgeries. These AI-controlled robots allow the surgeon to combine their judgment and knowledge with the control and precision of a robot, changing the way surgery is done in the future.
