Robotic-arm assisted surgery

Total knee and partial knee replacement

Robotic-assisted technology is changing the way knee replacement surgery is planned and performed. It combines the expertise of your surgeon with advanced tools designed to enhance precision and control during surgery.

With robotic assistance, your surgeon can create a personalized surgical plan based on the unique shape and condition of your knee. During the procedure, the technology helps the surgeon follow this plan with a high degree of accuracy – supporting the careful placement of implants and helping protect surrounding soft tissues.

For patients, this means a procedure that’s tailored to their individual anatomy, performed with consistency and attention to detail – all guided by their surgeon’s skill and experience.

Experience severe knee pain or stiffness caused by conditions such as osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, or other forms of joint degeneration.

Find that non-surgical treatments such as medication, physiotherapy, injections, or bracing – no longer provide enough relief or allow them to move comfortably.

Have early to mid-stage osteoarthritis that affects only part of the knee joint, rather than all three compartments.

Total hip replacement

Robotic-assisted technology is changing the way hip replacement surgery is planned and performed. It combines your surgeon’s skill and expertise with advanced tools designed to enhance precision, accuracy, and consistency during surgery. Before the procedure, detailed images of your hip joint help create a personalized surgical plan based on your unique anatomy. During surgery, the robotic system assists the surgeon in following that plan with a high degree of accuracy – supporting the proper placement and alignment of the implant while helping to preserve healthy bone and surrounding tissue. For patients, this approach can provide a more tailored experience and added confidence in their procedure. Many people appreciate that robotic-assisted techniques are designed to support smooth joint movement and a more natural feel after recovery.

Experience severe hip pain or stiffness caused by conditions such as osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, avascular necrosis, or other degenerative joint diseases.

Have not found enough relief with non-surgical treatments such as medication, physiotherapy, lifestyle changes, or joint injections.

The robotics difference

Robotic-assisted technology can help lead to better outcomes, like less pain1 and shorter recovery times1, compared to manual surgery.

In clinical studies, compared to manual surgeries, robotics:

  • Enabled surgeons to execute their surgical plans more.2,3
  • Protected soft tissue and ligaments from damage.4,6
  • Resulted in lower pain scores among patients surveyed 6 months after surgery than those who received conventional joint replacement.5
  • Resulted in better patient satisfaction scores among patients surveyed 6 months after surgery compared to those who received a conventional joint replacement.5

The journey of a CT-based robotic-arm assisted replacement surgery

Step 1 - Scanning

Before surgery, a CT scan of your knee or hip is taken and used to develop a 3D virtual model of your unique joint. This helps the surgical team understand your unique anatomy.

Step 2 - Planning

Next, the surgeon performs patient-specific surgical planning using the 3D model. They assess your bone structure, the severity of joint damage, overall alignment, and surrounding tissues. This allows them to determine the ideal implant size, placement, and alignment tailored to your anatomy.

Step 3 - Surgery

In the operating room, the surgeon uses a robotic-arm–assisted system to precisely remove arthritic bone and cartilage.
The technology creates virtual boundaries that provide feedback and help the surgeon stay within the pre-defined plan.
During the procedure, the system also provides real-time data on joint movement and soft-tissue tension, enabling the surgeon to make adjustments as needed for optimal accuracy.
