St John of God Subiaco Hospital first in Australia to install cutting-edge orthopaedic surgery robot

4 Aug 2025

The hospital, which was also the first in Australia to introduce the Mako robotic system in 2015, continues to build on its legacy of pioneering advancements that improve patient outcomes and surgical precision.

The Mako 4 represents the most advanced iteration of robotic-assisted technology for hip and knee joint replacement procedures. It features enhanced visibility, more precise mechanics, and improved software and data integration, all designed to support greater surgical accuracy and more complex procedures.

The device generates a 3D model of the patient’s joint prior to surgery, allowing surgeons to plan the procedure in detail based on the individual’s specific anatomy. During the operation, the surgeon guides the Mako’s robotic arm according to the patient’s pre-operative plan and 3D model, and uses real-time feedback from the system to optimally position the joint implant.

The first Mako 4-assisted procedure (an advanced total hip replacement) outside of the USA was performed on Thursday 24 July at St John of God Subiaco Hospital, continuing the hospital’s commitment to innovation in orthopaedics.

St John of God Subiaco Hospital Director of Medical Services Dr Frank Daly said the system is expected to provide significant benefits for both surgeons and patients.

“Many of our orthopaedic surgeons are confident the Mako 4 builds on ongoing advancements in orthopaedic robotic technology. It features a larger, high-definition display monitor and a camera with a wider field of view, which will improve their ability to see the surgical area. It is anticipated that this improved visibility will directly contribute to better accuracy and improved surgical workflow,” Dr Daly said.

“Studies have also shown that this technology can result in less post-operative pain, better mobility and a faster return to everyday activities.

“In addition, features of this new system are designed to assist with advanced total hip replacement and revision surgeries. These are often more complex procedures, typically required for patients with conditions that make surgery more challenging, including severe joint deformities, complicated bone anatomy, severe arthritis, failed previous surgery, or bone loss.”

“The Mako 4 also includes upgraded hardware which will support future software improvements as they become available, including capabilities for shoulder and spine surgery.”

“Another advantage is that the Mako 4 has a smaller footprint, making it easier to move between theatres and contributing to improved efficiencies and turnaround times. This will become increasingly important as demand for joint replacement surgery continues to grow.”

St John of God Subiaco Hospital has a long-standing reputation for surgical innovation and is widely regarded as a centre of excellence in orthopaedics, attracting leading surgeons who want to access the latest technologies.

St John of God Subiaco Hospital CEO Tina Chinery said the installation of the Mako 4 is another proud milestone in the hospital’s long history.

“To be the first hospital outside of the United States to adopt this next-generation surgical technology is a testament to our commitment to clinical excellence, and to providing our patients leading, world-class care,” she said.

“This commitment is also reflected in our ongoing investment in research across a wide variety of specialties, including orthopaedics.”
