Robotic orthopaedics

Robotic-arm assisted technology and 3D scanning for partial knee replacements or total hip replacements.

The procedure

Orthopaedic surgeons at Spire Murrayfield Hospital can now use Mako’s robotic-arm to assist during total hip replacements and partial knee replacements. The robotic technology provides a personalised surgical plan for joint replacement surgery.

CT scans are used to create patient-specific, 3-D modelling for pre-surgical planning. In the operating room, your surgeon follows the personalised surgical plan while preparing the bone for the implant. The Mako robotic-arm guides your consultant within pre-defined areas which prevent them from moving outside planned areas, avoiding the removal of healthy bone tissue.

As surgeons use the robotic-arm to resurface the knee or hip joint for the placement of implants, the robotic-arm uses real-time, inter-operative feedback, enabling a high degree of precision and accuracy in placing implants. Research studies have shown that compared to traditional surgery, Mako can perform joint replacement with two to three times’ greater accuracy1

How Mako works

Based on preoperative CT scans, the Mako system generates a 3-D model of a patient's knee or hip joint.

This 3D model is used by the surgeons to determine how much bone to remove, and where to place the implants that replace diseased sections of these bones.

Without Mako, surgeons use a burr saw to remove bone. They work by eye and experience - instead of looking at the bone itself to determine whether enough has been removed. Mako tracks healthy and diseased bone with a LCD panel. Mako shows bone that needs to be removed as green; and areas of healthy tissue (which shouldn’t be removed) appear in red. This allows unparalleled accuracy within about two millimetres.

With Mako, the surgeon operates the robotic-arm that is equipped with a saw. The surgeon is free to remove bone until he reaches the boundaries prescribed during the planning stages. If the surgeon attempts to move outside these boundaries, the saw will turn off. This helps the surgeon minimise the trauma to the hip or knee and preserves the maximum amount of healthy tissue.

Movement during surgery

Unlike alternative robotic systems which clamp directly onto the bone, Mako is capable of tracking the position of the leg throughout surgery. This is achieved as it is not fixed relative to the bone but uses an infrared camera to track the position of the robotic-arm and the position of reflective bone screws placed in the bone. This is of crucial advantage to Mako patients as it leaves the surgeon free to move, adjust and test the musculoskeletal function of the hip or knee throughout surgery.

What the surgeons say

Consultant Orthopaedic Surgeon, Mr Jonathan Cowie

“The future of orthopaedic surgery is poised to change forever. Mako allows me to perform with consistent accuracy in bone preparation, implant placement, and balancing of soft tissue. This is the joint replacement I would recommend for my friends and family.”

Consultant Orthopaedic Surgeon Mr Sam Patton

“These procedures are notoriously difficult to perform by hand. Mako makes this surgery more precise and reproducible. The best type of knee replacement is one that you forget that you have. Robotic surgery is a quantum leap in achieving this.”

Consultant Orthopaedic Surgeon, Mr Matt Moran

“This is cutting-edge technology for a more natural feeling joint and improved patient satisfaction after joint replacement.”

About Mako

Mako procedures have been carried out for over ten years now, with the first knee replacements being carried out in 2006, and the first hip replacement carried out in 2010 – both procedures were conducted in Florida USA. There are 300+ Mako systems assisting with surgery worldwide spanning 19 countries.

Over 70,000 robotic-arm assisted hip and knee procedures have been carried out so far and over 700 surgeons worldwide regularly perform Mako procedures.

Mako platform clinical success:

  • Significant primary clinical research has been conducted on the Mako platform:
    • 50+ peer reviewed clinical publications
    • 350+ scientific abstracts accepted at peer reviewed scientific conferences
    • Mako Robotic-Arm Assisted partial knee arthroscopy (PKA) resulted in 92% patient satisfaction at two years2
  • Mako Robotic-Arm Assisted PKA resulted in lower post-operative pain at day seven and more accurate implant placement than manual PKA in a randomised control trial3
  • Mako Robotic-Arm Assisted total hip arthroscopy (THA) demonstrated significantly higher modified Harris Hip scores and UCLA activity scores compared to manual THA at minimum one-year follow-up
