Mako Total Knee
?$max_width_1440$ "Mako 4 TKA and Q Guidance")
With over one million procedures completed, Mako Total Knee has transformed orthopaedics with its revolutionary technology and clinical outcomes. The unique features of Mako SmartRobotics™, and the powerful combination with Triathlon are designed to help surgeons achieve Functional Knee Positioning™ through 3D CT-based implant planning, dynamic joint balancing and AccuStop™ haptic technology. Mako Total Knee allows you to know more about your patient, so you can cut less.
Not all robotics are the same.
Mako makes the difference.
Mako was the only robotic system in the 2024 Australian Registry to show a difference compared to manual. When considered alone, the relative improvement in revision rates shown with Mako Total Knee were found to be significant versus no difference in revision rates at six years for the robotic assistance (inclusive of multiple technologies) category as a whole.3

What is Functional Knee Positioning™?
Functional Knee Positioning is a 3D process that personalizes each patient’s knee position with the goal of improving function. This is more than just a 2D alignment theory and can only be achieved in 3D, with Mako. This process is comprised of three elements: 3D CT-based planning, dynamic joint balancing and AccuStop™ haptic technology.
Step 1:
3D CT-based planning
- Create a 3D CT-based plan for each patient with Mako and Triathlon’s single radius design.
- Designed to optimize implant placement in the sagittal, transverse and coronal planes.
Step 2:
Digital Tensioner
- Assess ligament tension objectively using the proprietary Digital Tensioner.4
- No additional instrumentation or hardware.
- Audible and visual guidance during ligament assessment.
- This feature has been shown to have excellent intra-user repeatability (ICC ≥0.96) and inter-user reproducibility (ICC ≥0.90) minimizing subjectivity and potentially leading to a more predictable surgery.4
Dynamic joint balancing
- Balance the knee, in the medial and lateral compartments, by refining the implant position to accommodate the soft tissues.
Step 3:
AccuStopTM haptic technology
- Constrain the saw within the patient-specific virtual boundary, eliminating the need for cutting guides.
- Allows the surgeon to accurately execute the patient’s unique plan5 while protecting soft tissues6 when compared to manual cutting blocks.
The outcomes you expect.
The experience you deserve.
Mako Total Knee has shown...
Greater accuracy and precision to plan
Studies have shown 3D CT-based planning and haptic boundaries allow surgeons to deliver a more accurate and precise procedure to plan,3 with less soft tissue damage compared to manual.6,7
Less pain, fewer meds
Patients experienced less pain,8 and require less pain relief9 compared to manual total knee replacement.
Improved early recovery
A study has shown that Mako Total Knee patients hit postoperative goals earlier and were discharged home sooner when compared to patients who underwent manual surgery.8 Physical function scores have been shown to be favorable three-years post-surgery.10
Improved mid-term survivorship
In the 2024 Australian Registry, six-year survivorship of the Triathlon CR implanted with Mako had a relative improvement of 19% compared to manual. When implanted with a patella, the relative improvement compared to manual was 30%.3
