Q and A on Robotic-Assisted Surgery with Dr. Cameron Barton

1. What are the key benefits of robotic-assisted knee replacement surgery compared to traditional methods?

Robotic-assisted surgery offers greater precision and accuracy in placing the knee implant. This can potentially lead to a more balanced joint replacement and longer implant survivorship, although more research is needed to know for sure.

2. Can you explain how the robotic system helps improve the accuracy and precision during the procedure?

The robotic system uses advanced imaging technology to create a 3D model of your knee, allowing the surgeon to plan the procedure with great precision. During surgery, the robot helps guide the surgeon’s bony cuts, ensuring that the implants are placed in the optimal position for alignment, function, and stability.

3. How does the robot interact with your movements during the surgery? Is it fully automated, or does the surgeon still have full control?

The robot does not perform the surgery on its own. It is more of a navigation tool. The surgeon still has to advance the saw and make the cuts.

4. How does robotic-assisted surgery affect the recovery time and rehabilitation process for patients?

Since our surgery center was created, we have been constantly looking for ways to make recovery easier for joint replacement patients. Some of these improvements include pre-operative pain blocks, intra-operative peri-articular pain blocks, and postop multi-modal pain control strategies. We also use soft tissue respecting approaches, to help limit soft tissue injury during surgery, to help make recovery easier. Already >90% of our joint replacement patients go home same day surgery. Robotic assisted surgery has not really shown to make much of a difference with recovery, so that is not really supported by research. The main difference between robotic assistance and traditional methods hinges on precise component positioning.

5. Are there specific types of patients or conditions that benefit most from robotic-assisted knee replacements?

Robotic-assisted knee replacements can be especially beneficial for patients with complex joint deformities, severe arthritis, or those with prior hardware in place, where traditional intramedullary guide rods could not be used.

6. What are some common misconceptions patients have about robotic-assisted knee replacement surgery?

Some patients may think the robot performs the surgery on its own, but it is the surgeon who controls the robotic arm and plans it. Some may fear that the robot could malfunction, but these systems are designed with multiple safeguards and have been shown to improve the accuracy of procedures. It is also very easy to convert to a standard knee replacement if needed at any point during the surgery.

7. How does the robot assist in customizing the knee implant to a patient’s individual anatomy?

The robot uses intra-operative mapping technology to create a detailed 3D model of your knee. This allows the surgeon to choose the best implant size and position based on your specific anatomy.

8. Have you seen any differences in complication rates or patient outcomes between robotic-assisted and traditional knee replacement surgeries?

Studies have shown that robotic-assisted knee replacements can be done safely with similar complication rates compared to traditional methods. Overall pain and function outcomes seem to be similar.
