Robotic Knee Replacement: Precision, Benefits & Recovery | SBJI

Knee replacement surgery is a transformative procedure for those struggling with chronic knee pain and reduced mobility. With advancements in medical technology, robotic-assisted knee replacement has emerged as a more precise and efficient alternative to traditional methods. At Sunshine Bone and Joint Institute (SBJI), we are committed to educating our patients about these cutting-edge options. Here’s an in-depth look at robotic total knee replacement, its mechanism, and how it enhances the outcomes for those seeking relief from knee pain.

What Is Robotic Total Knee Replacement?

Robotic total knee replacement is a form of knee surgery where a robotic arm or assistance system is used to improve the accuracy and alignment of the knee implant. This technology allows the surgeon to plan and execute the surgery with a high degree of precision, based on a patient’s unique anatomy. By integrating robotics into knee replacement procedures, surgeons can reduce complications and help patients achieve a more natural range of motion and function after surgery.

How Does Robotic-Assisted Knee Replacement Work?

The robotic total knee replacement procedure involves three main stages: preoperative planning, surgical execution with robotic assistance, and post-operative alignment verification. Here’s how each stage enhances the surgical process:

1. Preoperative Planning with 3D Imaging

Before the surgery, a 3D scan or CT scan of the patient’s knee is taken. This detailed imaging provides a precise map of the knee structure, helping the surgeon understand the specific bone and joint anatomy. Using this data, a personalised surgical plan is developed, detailing the exact positions and angles for implant placement. This level of planning allows surgeons to predict and avoid potential challenges, optimising the surgery for each patient.

2. Precision Surgery with Robotic Assistance

During the surgery, the robotic system assists the surgeon by providing real-time feedback and guiding the surgical instruments. Contrary to popular belief, the robot does not perform the surgery independently. Instead, it serves as a tool that enables the surgeon to operate with unmatched accuracy. The robotic arm assists in bone cutting and implant positioning based on the preoperative plan. This guidance helps in achieving precise cuts, reducing the risk of errors, and ensuring that the implant fits perfectly. Because of the robot’s assistance, the risk of tissue damage is minimised, leading to a shorter recovery period and potentially less postoperative pain.

3. Verification and Alignment

After the implant is placed, the robotic system provides an alignment verification, ensuring that the implant is positioned exactly as planned. This step is crucial because even slight misalignments can lead to premature implant wear, discomfort, or reduced joint mobility. By confirming proper alignment, robotic-assisted knee replacement enhances the longevity of the implant and improves overall knee function.

Benefits of Robotic Total Knee Replacement

• Robotic-assisted knee replacement offers multiple advantages over traditional methods:
• Greater Accuracy: The robotic system allows for precise implant placement, reducing the risk of alignment issues and complications.
• Personalised Fit: With 3D imaging, the surgery is customised to each patient’s anatomy, leading to a more natural feel and improved joint function.
• Reduced Recovery Time: Minimally invasive techniques, combined with precision, often lead to a quicker recovery and less pain, allowing patients to resume daily activities sooner.
• Enhanced Implant Longevity: Proper alignment and fit reduce wear and tear on the implant, potentially increasing its lifespan and reducing the likelihood of revision surgeries.

Who Can Benefit from Robotic Knee Replacement?

Robotic total knee replacement is suitable for patients with severe arthritis, cartilage damage, or chronic knee pain that limits their mobility and quality of life. Ideal candidates are those who have not responded well to conservative treatments, such as physical therapy or medication. However, a consultation with an orthopaedic specialist is essential to determine if robotic-assisted surgery is the best option, as individual conditions vary.
