Why Choose MJ Naidu Hospital for Your Knee Replacement? Introducing the Pixee Medical Knee+ System

With the recent developments in MedTech, knee replacement surgeries have undergone a shift from the early traditional approach. AR technology has been the trailblazer, providing more anatomic information for each patient, allowing surgeons to be precise and perform cuts to the specific anatomy. This will translate to better outcomes for the patients as opposed to the past methods of a one-size-fits-all solution.

MJ Naidu Hospital is proud to introduce the revolutionary Pixee Medical Knee+ system, marking a significant advancement in our commitment to precision-driven surgical care.

Let’s dive more deeply into how this cutting-edge AR technology is shaping the future of knee replacement surgery.

What Is the Pixee Medical Knee+ System?

The Knee+ is an innovative augmented reality solution specifically designed for total knee arthroplasty procedures. This system provides real-time navigation of angular values and resection levels, helping surgeons achieve implant positioning accuracy with robotic-like precision.

The system features a redesigned interface combined with high-precision surgical tools to provide seamless, personalized guidance throughout the procedure. What sets the Knee+ apart is its intuitive design that allows surgeons to maintain complete control while benefiting from advanced AR visualization.

Key Advantages of the Knee+ System:

Surgeon-Controlled Precision: The system allows surgeons to accurately align the position of total knee components through a completely surgeon-controlled headset, miniaturizing and streamlining total knee surgery with a very small back table footprint.

No Pre-Operative Scans Required: The augmented reality system integrates into existing workflows and requires no pre-op scans while achieving implant positioning with robotic-like precision.

Proven Track Record: The system has already been used in over 10,000 procedures in more than 20 countries, demonstrating its reliability and effectiveness.

FDA-Cleared Technology: The Knee+ has received FDA 510(k) clearance, ensuring it meets the highest safety and efficacy standards for surgical navigation systems.

What Is Augmented Reality in Knee Surgery?

Augmented Reality (AR) in knee surgery brings digital technology right into the operating room, giving surgeons a real-time, view of your knee as they work. With the Knee+ system, you can think of it as a high-tech overlay that guides each step, helping ensure your knee implant is placed with incredible accuracy, tailored to your unique anatomy.

Why It Matters for You:

Smaller incisions for less surgical trauma and faster healing
Pinpoint precision helps ensure a better fit and more natural movement
Shorter recovery times to help you get back on your feet sooner
Enhanced surgical accuracy without the need for additional pre-operative imaging

AR vs. Robotic-Assisted Knee Surgery: Understanding the Difference

While both technologies aim to improve surgical outcomes, there are fundamental differences between augmented reality systems like the Pixee Medical Knee+ and traditional robotic-assisted surgery systems currently available in the market.

Current Robotic Systems in the Market:

MAKO SmartRobotics (Stryker): A semi-active robotic arm-assisted system that relies heavily on preoperative CT imaging for surgical planning. The MAKO system only captures virtual gap data in full extension and 90° of flexion.

ROSA Knee System (Zimmer-Biomet): A semi-active robotic arm-assisted system that offers touchscreen interface and continuous visual feedback. However, recent studies have shown unsatisfactory accuracy in calculating certain critical angles.

VELYS Robotic-Assisted Solution (Johnson & Johnson): Designed to work in conjunction with ATTUNE Knee System implants, focusing on increased accuracy and precision.

CORI Surgical System (Smith & Nephew): Another semi-active robotic arm system with touchscreen capabilities.

Comparative Advantages of AR Systems vs. Robotic Systems:

Feature	Pixee Medical Knee+ (AR)	Traditional Robotic Systems
Pre-operative Requirements	No CT scans required	Require preoperative CT imaging
Setup Complexity	Minimal setup, small footprint	Large robotic arms, extensive setup
Surgeon Control	Complete surgeon control	Semi-active assistance with some limitations
Workflow Integration	Seamless integration	May require workflow modifications

Clinical Outcomes Comparison:

AR System Advantages: The Pixee Medical Knee+ system achieves similar precision outcomes without the complexity, cost, and pre-operative imaging requirements of robotic systems. Some studies suggest cost savings in episode-of-care costs with advanced surgical systems.

Why Choose AR Over Robotic Systems?

Accessibility: No need for expensive pre-operative CT scans makes the procedure more accessible to patients.
Efficiency: Streamlined workflow without the setup time required for robotic arms and extensive calibration.
Surgeon Autonomy: Maintains complete surgeon control while providing precision guidance.
Adaptability: Can be integrated into existing surgical workflows without major infrastructure changes.

What are the steps involved in using the Knee+ AR Technology?

Unlike traditional approaches or even standard robotic systems, the Knee+ system enhances the surgeon’s capabilities with real-time, data-rich visualization and decision-making tools while maintaining complete surgeon control.

Here’s how this advanced system works from start to finish:

Step 1: Streamlined Setup

The Knee+ system requires minimal setup with its compact design and small back table footprint. Unlike traditional systems, no pre-operative CT scans or extensive planning sessions are required, making the process more efficient for both patients and surgical teams.

Step 2: Real-Time Calibration

During surgery, the system performs real-time calibration using the patient’s anatomical landmarks. The cutting planes are oriented with respect to the mechanical axes of the patient and are calculated specifically for each individual case.

Step 3: Sensor-Driven Navigation

Small sensors provide dynamic feedback while allowing the surgical team to move freely. The system offers precise navigation of angular values and resection levels throughout the procedure, ensuring optimal implant positioning.

Step 4: Enhanced AR Visualization

Wearing the AR headset, the surgeon sees an overlay of the patient’s anatomy and surgical data directly in their field of view. This setup eliminates the need to glance away at external monitors, creating a more intuitive and immersive operating environment. Measurements, alignment guides, and positioning data appear layered over the actual knee, improving both confidence and accuracy.

Step 5: Precision-Guided Bone Cuts

The AR system guides precise bone cuts that are tailored to the patient’s unique anatomy. The surgeon maintains complete control while benefiting from real-time feedback and guidance, ensuring optimal implant fit and alignment.

Step 6: Functional Optimization

The system integrates functional measurements and ensures proper ligament tension and soft tissue balance, maintaining natural joint movement patterns for optimal post-operative outcomes.
