The article delves into the reasons why robotic machines have become an essential tool in orthopedic surgery and also shows how they are designed, how effective they are, the types of them, and what it means for the future of orthopedic surgery.
What is Robotic Orthopaedic Surgery?
Orthopedic surgery aided by robots is the one where surgical robots are used to carry out complicated processes involving the bones, joints, ligaments, and muscles of the human body. These machines make it possible to carry out complex surgeries with ease and more accurately than ever before.
Orthopedic robotic surgery is most often found in joint replacement procedures (knee and hip arthroplasties), spine surgery, and some fracture fixation. The robots do not operate on the patients by themselves, rather they help the surgeon to improve the visual field for the procedure, achieve better accuracy and control for the surgical tools used. This leads to better and more predictable results with tissue preservation and smaller scar related to the incision.
How Robotic Orthopaedic Surgery Machines Work
Robotic orthopedic surgery machines are highly sophisticated systems that integrate various components, including imaging technology, robotic arms, and specialized software, to assist surgeons during procedures. Here is a breakdown of how these machines typically work:
1. Preoperative Planning
The process begins with detailed imaging of the patient’s anatomy. Advanced imaging techniques such as CT scans, MRI, or X rays are used to create a 3D model of the area to be operated on. This data is fed into the robotic system’s software, which helps the surgeon plan the surgery with pinpoint accuracy. The preoperative plan includes the exact positioning of implants, the alignment of bones, and the precise areas to be operated on.
2. Intraoperative Guidance
During surgery, the robotic system assists the surgeon by providing real time visual and tactile feedback. The robotic arm, equipped with surgical instruments, operates with sub millimeter accuracy, ensuring that incisions and bone cuts are made precisely according to the preoperative plan. This level of accuracy is crucial in orthopaedic surgeries, where even slight deviations can affect the functionality and longevity of joint replacements.
3. Surgeon Controlled Operation
The surgeon remains in full control throughout the procedure. The robotic system acts as an extension of the surgeon’s hands, providing enhanced stability and precision. The system’s robotic arm can filter out any unintentional hand movements (like tremors), allowing for smoother and more precise movements. This ensures that the surgeon can work within the tight confines of the surgical area without causing unnecessary damage to surrounding tissues.
4. Real Time Adjustments
One of the key advantages of robotic orthopaedic surgery machines is their ability to provide real time data and make adjustments during surgery. If the surgeon identifies the need for a modification during the procedure, the robotic system can accommodate these changes without compromising accuracy. This flexibility is particularly important in complex surgeries, where unpredictable issues can arise.
5. Postoperative Analysis
After the surgery is complete, the robotic system can provide detailed postoperative data to evaluate the accuracy of the procedure. This helps in tracking the success of the surgery and can provide valuable insights for postoperative care and rehabilitation.
Benefits of Robotic Orthopaedic Surgery Machines
The introduction of robotic systems in orthopaedic surgery has brought numerous benefits, both for surgeons and patients. Here are some of the key advantages:
1. Increased Precision
Robotic systems offer unparalleled precision in bone cutting, implant positioning, and soft tissue management. This precision is crucial in procedures like joint replacements, where the alignment of implants can significantly impact their longevity and functionality. Proper alignment also reduces the likelihood of complications such as implant failure or the need for revision surgeries.
2. Smaller Incisions and Less Invasive Procedures
Robotic assisted surgeries are often performed using minimally invasive techniques, meaning smaller incisions and less damage to surrounding tissues. This results in reduced scarring, less pain, and a faster recovery time for patients. Smaller incisions also lower the risk of infections and postoperative complications.
3. Improved Implant Longevity
By ensuring that implants are placed with utmost accuracy, robotic orthopaedic surgery machines help improve the longevity of joint replacements. Properly aligned implants are less likely to wear out prematurely, reducing the need for costly and invasive revision surgeries down the line.
4. Reduced Surgeon Fatigue
Traditional orthopedic surgeries can be physically demanding for surgeons, requiring prolonged periods of intense focus and precision. Robotic Orthopaedic Surgery Machines alleviate some of this strain by providing assistance in stabilizing surgical instruments and reducing the need for repetitive motions. This support from Robotic Orthopaedic Surgery Machines leads to reduced surgeon fatigue, which can translate to more consistent results during surgery.
5. Real Time Adjustments and Feedback
Robotic systems provide surgeons with real time feedback during the procedure, allowing them to make adjustments as needed. This flexibility is particularly important in complex surgeries, where unpredictable changes can occur. The ability to adapt during the surgery ensures that the outcome is optimal for the patient.
6. Shorter Recovery Times and Improved Patient Outcomes
Patients who undergo surgeries with Robotic Orthopaedic Surgery Machines often experience shorter hospital stays, quicker recovery times, and less postoperative pain. The minimally invasive nature of these procedures allows patients to return to their normal activities sooner, with fewer complications. Additionally, studies have shown that patients undergoing joint replacements with Robotic Orthopaedic Surgery Machines report higher satisfaction rates due to better functional outcomes.
Types of Robotic Orthopaedic Surgery Machines
Several types of robotic systems are currently being used in orthopaedic surgery. These systems vary in terms of design, functionality, and the types of procedures they support. Some of the most prominent robotic orthopaedic surgery machines include:

It is commonly employed in partial and total knee replacements, as well as hip replacements. The MAKO system allows surgeons to create a personalized surgical plan using 3D models of the patient’s anatomy. During surgery, the robotic arm assists in positioning the implant with exceptional accuracy, minimizing the risk of misalignment.
2. ROSA Robotic System
The ROSA (Robotic Surgical Assistant) system, developed by Zimmer Biomet, is another leading platform in orthopedics and is part of the cutting edge advancements in Robotic Orthopaedic Surgery Machines. It is used in a variety of procedures, including total knee and hip replacements. The ROSA system provides real time data and imaging to help the surgeon during surgery, improving precision and reducing the likelihood of complications. Robotic Orthopaedic Surgery Machines, such as ROSA, are also used in spinal surgeries, offering assistance in complex procedures that require precise navigation of the spine.
3. Navio Surgical System
The Navio Surgical System, created by Smith & Nephew, is a handheld robotic platform used for partial and total knee replacements. Unlike other systems that require preoperative imaging, Navio allows surgeons to create 3D models intraoperatively, using real time data during the procedure. This flexibility makes Navio a valuable tool for surgeons who want to make adjustments on the fly without relying heavily on preoperative imaging.
