Robotic Knee Replacement Partial

Robotics-assisted Planning for Better Surgical Outcome

While it may seem counterintuitive, replacing only part of a knee joint can be more challenging than replacing the entire joint. This is because partial knee replacement must achieve an exact balance between the new implant – made of metal and plastic components – and the remaining portions of your natural anatomy made of bone and cartilage. As a result, one of the primary challenges of all partial knee replacements is accurately positioning the implant for each unique patient. Even minor changes in an implant’s size or placement can cause the knee to function poorly or result in early failure of the implant and the need for future surgery.

The Robotic Knee Surgery System, Ahmedabad, Gujarat addresses the challenge of partial knee replacement by using both computer and robotic assistance to accurately map the surface of your knee, align your implant to your anatomy, and physically remove the bone necessary to place your new implant.3 This added level of assistance is important because implant alignment is a crucial factor in determining how long the implant will last. 5, 6

Robotic Knee Surgery without Radiation

Other robotic knee replacement systems use computerized tomography, or CT, scans to help a surgeon visualize a patient’s knee anatomy. While CT scans are effective at showing the layers of knee anatomy, they can expose the patient to potentially harmful radiation. In fact, a single CT scan is equivalent to the radiation exposure received in 48 chest X-rays.4

The Robotic Knee Surgery system, Ahmedabad, Gujarat eliminates the need for CT scans by using an advanced computer program (similar to GPS navigation on your phone) to collect anatomic and alignment information about your knee. Once captured, this information is used to build an accurate, computer-rendered 3D model of your knee that your surgeon will use to plan your surgery.

NAVIO Robotics-assisted Partial Knee Replacement Surgery

After all of the information about your knee is gathered and your surgical plan is created, your surgeon will use a robotic Knee surgery tool (the NAVIO handpiece) to physically remove the damaged surface of your bone so that your new implant fits properly. Using the same 3D model of your knee, the handpiece is able to differentiate between the damaged areas that need to be removed, and the healthy areas that will remain. The NAVIO handpiece uses a burr that removes damaged bone for your implant.

The NAVIO Knee Replacement system, Ahmedabad, Gujarat doesn’t replace your surgeon. Rather, it assists your surgeon by adding an extra layer of planning to the procedure.

Partial Knee Replacement with Traditional Techniques

By comparison, traditional surgical methods for partial knee replacement use a combination of long, metal IM (Intra-medullary) rods that are drilled into the central bone canal to determine anatomic alignment and mechanical cutting guides that help guide a saw blade as it removes the bone necessary to place the implant. The Robotic Surgical System, Ahmedabad, Gujarat helps tailor your partial knee replacement procedure to your unique knee anatomy without the need for intramedullary rods or cutting guides.
