Robotics — Joint Replacement

MISSO™ Robotic System

An AI-enabled robotic platform combining personalised surgical planning, optical tracking and precise bone preparation for knee replacement.

The MISSO™ Robotic System is designed to assist surgeons throughout robotic-assisted joint replacement, from digital pre-operative planning to controlled execution in the operating room.

The platform integrates patient-specific planning, real-time optical tracking and a 6-axis robotic arm to translate the surgical plan into precise femoral and tibial bone preparation.

Rather than replacing surgical decision-making, the system provides the surgeon with digital planning tools, intra-operative feedback and robotic assistance intended to improve consistency and control throughout the procedure.

The system

Planning, tracking and robotic execution within one integrated workflow

The robotic platform is organised around three complementary elements: a vision and computing cart, a collaborative robotic arm and dedicated planning software.

Pre-operative imaging is used to reconstruct patient anatomy and create a personalised surgical plan. AI-assisted software supports segmentation and implant planning, including automatic implant size estimation and detection of potential component overhang or femoral notching.

During surgery, optical tracking continuously relates the patient’s anatomy to the digital plan. The robotic arm then provides controlled multi-directional movement for bone preparation while allowing the surgical team to monitor and adjust the workflow.

Vision Cart

The vision cart serves as the computing and navigation centre of the platform. It incorporates a 27-inch medical-grade touch display, optical tracking technology, integrated keyboard and trackpad, and the operating software used throughout the procedure.

Robotic Arm

The collaborative robotic arm provides six axes of movement and is engineered for multi-directional manoeuvrability around the operating field. Integrated sensing and bone-tracking capabilities support controlled execution as patient anatomy is monitored during the procedure.

Digital Planner

The planning environment uses patient imaging to generate a personalised three-dimensional surgical plan. AI-assisted tools support segmentation, implant sizing and assessment of implant positioning before robotic execution.

Key Features

Technology designed for planning accuracy, real-time tracking and controlled execution

The robotic platform combines optical navigation, medical-grade visualisation and dedicated bone-preparation instrumentation with a multi-axis robotic arm to support the surgical workflow from planning through execution.

High-precision optical tracking

The platform incorporates an NDI Polaris optical tracking system to monitor the spatial relationship between patient anatomy, tracked instruments and the robotic workflow.

Real-time positional information allows the system to relate intra-operative anatomy to the digital surgical plan.

27 inch medical grade robotic surgery touchscreen

27-inch medical-grade touchscreen

A 27-inch medical-grade touch-enabled display provides the visual interface for planning, navigation and procedural information.

The integrated user interface is designed to centralise relevant digital information within the operating-room workflow.

Robotic femoral and tibial cutting guide

Dedicated cutting guide

A dedicated cutting guide supports preparation of the femur and tibia according to the planned implant position and resection parameters.

The instrumentation is integrated into the robotic workflow to translate digital planning into controlled bone preparation.

Advanced drill system

The robotic workflow incorporates dedicated drilling instrumentation for bone resection and preparation of implant peg holes.

The system allows these preparation steps to be performed in relation to the planned implant geometry and tracked patient anatomy.

Six axis robotic arm for joint replacement

6-axis collaborative robotic arm

The system houses a 6-axis collaborative robotic arm designed for precise multi-directional movement during bone preparation.

Adaptive tracking and integrated sensing allow robotic execution to remain connected to the patient’s tracked anatomy throughout the procedure.

Clinical workflow

Robotic-assisted knee replacement

The platform is designed to support surgeons during knee replacement procedures through patient-specific planning and robotic-assisted bone preparation.

Pre-operative imaging is converted into a three-dimensional representation of the patient’s anatomy. Implant position and size can then be planned digitally before surgery.

Intra-operatively, optical tracking links the surgical anatomy to the digital plan. The surgeon remains responsible for the procedure and can review or modify relevant planning parameters before robotic bone preparation is performed.

Use of the robotic platform, compatible implants and associated instrumentation must follow the applicable Instructions for Use, approved indications and local regulatory requirements.
