New-gen Treatment for Knee Replacement: The Revolutionary Role of Robotic Surgery in Orthopaedics
In the ever-evolving field of orthopaedics, technological advancements have significantly reshaped how joint replacement surgeries are performed. Among these innovations, robotic-assisted surgery has emerged as a groundbreaking development, particularly in knee replacement procedures. This new-generation treatment combines precision, personalization, and improved patient outcomes, marking a paradigm shift in orthopaedic care.
What is Robotic-Assisted Knee Replacement?
Robotic-assisted knee replacement involves the use of advanced robotic systems to assist surgeons in performing highly precise knee replacement procedures. These systems are not autonomous robots but rather sophisticated tools that enhance the surgeon's capabilities. By integrating 3D imaging, preoperative planning, and intraoperative guidance, robotic systems enable unparalleled accuracy in aligning and positioning implants.
How Does Robotic Surgery Work?
The robotic-assisted knee replacement process begins with a detailed preoperative plan. Advanced imaging techniques such as CT scans create a 3D model of the patient’s knee, providing a comprehensive view of the joint’s anatomy. This model helps surgeons develop a tailored surgical plan, addressing each patient’s unique needs.
During the procedure, the robotic arm or system assists the surgeon by:
This precision reduces the risk of human error and enhances the longevity and functionality of the knee implant.
Advantages of Robotic Knee Replacement
Robotic-assisted knee replacement offers several benefits over traditional methods:1. Unparalleled Precision:
A meta-analysis of 12 randomised controlled trials revealed that rTKR achieves more precise placement of prosthetic components and improved joint alignment accuracy compared to conventional TKR (cTKR). The study showed significantly fewer outliers in various joint angles, including the hip-knee-ankle angle (1).
2. Reduced Soft Tissue Damage:
A cadaveric study found mild posterior cruciate ligament injuries in 28% of cTKR patients, while none were observed in the rTKR group. Preserving periarticular soft tissue is crucial for faster recovery and better outcomes.
3. Decreased Blood Loss:
A 2021 study demonstrated that patients undergoing rTKR exhibited a 23.7% reduction in blood loss compared to cTKR. This significant difference also translated to an 83%relative risk reduction in the likelihood of receiving a blood transfusion (1).

4. Potential Cost Savings:
The same study revealed that the 90-day knee-related cost for the VRAS cohort was lower than other robotic technologies, suggesting potential economic benefits alongside clinical improvements.
Robotic Surgery vs Traditional Knee Replacement
While traditional knee replacement techniques have proven effective for decades, robotic-assisted surgery offers a level of precision and customization that manual methods cannot match. Traditional methods rely heavily on the surgeon’s skill and experience, whereas robotic systems provide consistent and reproducible results.
Who Can Benefit from Robotic-Assisted Knee Replacement?
Robotic-assisted knee replacement is suitable for patients with advanced osteoarthritis, rheumatoid arthritis, or other degenerative joint conditions causing severe knee pain and disability. However, not every patient may require or qualify for this advanced technique. A thorough evaluation by an orthopaedic specialist is essential to determine the best course of treatment.
As technology continues to evolve, robotic-assisted surgery is poised to become the gold standard for joint replacement procedures. With ongoing research and development, these systems are expected to become more accessible and affordable, further improving patient outcomes worldwide.
