Simply put, surgical navigation is surgery with the assistance of a computer.  Computers have become a part of, and changed, our everyday lives.  They continue to improve how we perform simple and complex tasks, with increased accuracy and efficiency.

Activities normally associated with labor intensive manual instruments, like, for example, mounting and balancing tires for your car, are now performed faster and with greater precision using the assistance of computers.

OMNIlife science™, Inc. believes that your surgery should not be any different, and that use of a computer enables surgeons to achieve greater accuracy during the knee replacement procedure1.

 

What is ARTTM?

ARTTM stands for APEX Robotic TechnologyTM.  It is an advanced, restorative surgical solution that enables orthopedic surgeons to perform total knee replacement surgery utilizing cutting-edge computer-assisted techniques, including a patented BONE MORPHINGTM technology and an intelligent robotic cutting guide.  This dynamic combination allows for precise bone resections and an optimized implant position based on each individual patient’s anatomy2. ARTTM empowers surgeons and hospitals to address the specific needs of a large and growing population suffering from knee pain due to osteoarthritis.

 

Who is OMNI?

OMNI is committed to the pursuit of excellence in everything that we do.  We are an industry leader when it comes to advanced orthopedic implant design and we offer technologies that allow our surgeons to more accurately perform knee replacement surgery.   We believe in innovation, and that is why we provide knee replacement solutions such as ARTTM.

 

Details of the ART ™ Surgical Navigation System

iBlock® Cutting Guide

iBlock is an intelligent instrument, which automatically positions a bone cutting guide exactly as planned by the surgeons, therefore enabling surgeons to perform fast and accurate bone cuts that improve implant alignment2.

iBlock’s versatility is a unique feature that offers the surgeon the option of customizing her surgical protocols.

  • Easily mounts to the femur using drill pins
  • Minimally invasive
  • Robotic Saw Guide Positioning
  • Maximize Surgeon Control
  • Increased Accuracy & Reliability
  • Micrometric Adjustability

What is BONE MORPHING?

BONE MORPHING® allows the surgeon to build a patient-specific 3D model of the knee in real time in order to perform a virtual surgical plan prior to making any critical bone cuts. Once the plan is completed and visualized, APEX Robotic TechnologyTM provides the surgeon the ability to carry out this surgery with greater accuracy than with conventional computer-assisted methods.2 If needed, ARTTM instrumentation allows for simple, micrometric adjustment intra-operatively, ensuring that the knee joint will be aligned and well-balanced.

 

APEX Robotic TechnologyTM offers the following features and benefits:

  • Patented three-dimensional BONE MORPHING® Technology
    • Our navigation system was built around its navigation-specific instruments which optimize the surgical workflow and increases the efficiency of the operating room.
    • One study showed that the adjustable cutting block significantly reduced tourniquet time when compared to conventional cutting blocks in a navigated surgical setting(Suero). This reduction may increase the cost effectiveness of computer-assisted surgery.
  • Precise Mechanical Alignment
    • APEX Robotic TechnologyTM uses our BONE MORPHING® technology along with a proprietary robotic cutting guide to plan and execute femoral resections. This advanced technology allows the surgeon to reproduce the leg’s mechanical axis quickly and easily.
    • Studies have shown that ARTTM gives you significant improvements in bone cutting precision when trying to reproduce ideal leg alignment2.
    • Well-defined navigation algorithms and adjustable resection guides enable the surgeon to accurately reconstruct the mechanical axis of the patient’s limb.
  • Customized Workflow
    • Surgeons can customize their workflow to closely match their current technique.  Whether your focus is on measured resection, gap balancing, or something in-between, we can set your profile so that the software will follow your preferred workflow every step of the way.
  • Intra-Operative Kinematic Leg Assessment
    • Real time assessment of limb alignment and the soft tissue situation can be made at any time during the procedure whether pre-operative or post-operative.
  • Efficient Surgical Instruments
    • Our navigation system was built around its navigation-specific instruments which optimize the surgical workflow and increases the efficiency of the operating room.
    • One study showed that the adjustable cutting block significantly reduced tourniquet time when compared to conventional cutting blocks in a navigated surgical setting5.  This reduction may increase the cost effectiveness of computer-assisted surgery.

 

What benefit does surgical navigation provide to me?

Computers have improved how we perform complex tasks in our daily lives, and this includes joint replacement surgery.  Surgical navigation uses specialized tools along with a computer to achieve more consistent results with greater accuracy.3 For those undergoing total knee replacement surgery, this means an improved alignment of the knee implant which will extend the life of the implant as well as reduce post-operative pain and complications.4

Why is ARTTM (APEX Robotic TechnologyTM) an added value over conventional navigation?

ARTTM combines the benefits of surgical navigation with a patented bone-morphing technology (creating a 3D model of your knee) and a robotic cutting guide.  All these things together allow the surgeon to make critical decisions during surgery based on the patient’s specific anatomy.  The robotic cutting guide allows the surgeon to achieve a high level of precision which results in an optimized implant position for the patient.

Does the robotic cutting guide do the surgery?

No. Because each individual is unique in their anatomy the surgeon will still make every decision during the operation and this includes making all of the necessary bone and soft tissue cuts on his/her own.  Apex Robotic Technology, or ARTTM, will help maximize the surgeon’s ability to provide the best possible outcome.

What about these “patient-specific cut blocks” I’m hearing about?  Wouldn’t that be a better solution?

We don’t believe so. OMNI has spent their entire life as a manufacturer providing the best solutions based on science and clinical results.  There are many potential drawbacks to patient-specific cut blocks with the biggest risk being that all of the bone resections are pre-planned so that if unforeseen circumstances are encountered intra-operatively, making adjustments can be difficult.  Surgical navigation with ARTTM gives the surgeon flexibility to make fine-tuned adjustments during the operation as well as provides real time interactive assessment of your joint function.  The surgeon is prepared to execute the procedure the way he intended.

ART Surgical Protocol

Acquisition: Thanks to the ART patented Bone-Morphing Technology (BM), the system computes the specific anatomy of the knee joint as the surgeon digitizes the bone.

Navigation: ART software and instruments help the surgeon to position cutting guides with a high degree of precision.

Fine Adjustment: The knee prosthesis is implanted and the surgeon performs a final check and ligament balancing.
