PROTEOR Introduces QUATTRO 2, Revolutionizing Microprocessor Knee Technology

PROTEOR Unveils QUATTRO 2: Transforming the Future of Prosthetic Technology

In a significant advancement in prosthetic technology, PROTEOR launched the QUATTRO 2, the latest iteration of its renowned microprocessor knee system, on July 7, 2026, in the United States, with a worldwide release scheduled for September 2026. This new platform builds on the solid foundation laid by its predecessor, the original QUATTRO, while introducing key enhancements aimed at improving user experience and clinical outcomes.

Evolution of the QUATTRO Platform

Instead of completely overhauling a system that has earned the trust of health care professionals and patients alike, PROTEOR adopted a strategy of refinement and enhancement. This resulted in the creation of a microprocessor knee that is not only more intuitive and responsive but also more durable, addressing the real-life demands that users face daily. The development involved collaboration with prosthetists, rehabilitation specialists, and individuals living with limb loss, ensuring that QUATTRO 2 meets the diverse needs of its users.

Eric Ferris, Vice President of Global Marketing & Product Management at PROTEOR, emphasized the commitment of the company to delivering products that enhance movement and build confidence. "With QUATTRO 2, we took a successful platform and made it even better by focusing on enhancements that directly benefit users and clinicians alike. The goal was clear: to help people move more naturally and confidently," he stated.

Key Features and Innovations

QUATTRO 2 is packed with features designed to streamline the user experience while offering reliable performance. Here are some of the significant advancements:

- Stair Ascent Functionality: This feature provides users with a more natural and intuitive experience when climbing stairs.
- IP68 Rating: The knee is highly resistant to dust and water, making it suitable for various environments and activities.
- Increased Weight Limit: The patient weight capacity has been raised to 330 pounds (150 kg), accommodating a broader range of users.
- USB-C Charging Option: For added convenience, QUATTRO 2 includes an optional USB-C charging cord, offering users flexible charging options.
- Tenfold Processing Power: With ten times the processing power of its predecessor, QUATTRO 2 delivers enhanced real-time responsiveness, easily adapting to changes in terrain and movement patterns.

These advancements not only improve the prosthetic experience but also empower users to engage more fully in life, focusing less on their equipment and more on living independently.

A New Standard in Prosthetic Technology

The launch of QUATTRO 2 signifies that innovation in the prosthetic sector transcends mere mechanical enhancements. The emphasis is now on how well the technology integrates into daily life, fostering confidence in movement across various settings—be it at work, during leisure activities, or amidst family engagements.

Ferris articulated this sentiment, noting, "Innovation is about more than just adding new features. It’s about eradicating barriers, supporting clinicians in their work, and enabling users to take part in every aspect of their lives." PROTEOR’s dedication to advancing movement through thoughtful innovation resonates throughout the design and functionality of QUATTRO 2.

As QUATTRO 2 gears up for its international launch in September 2026, PROTEOR continues to solidify its role as a leader in prosthetics and orthotics. With over 110 years of experience and a presence in more than 80 countries, PROTEOR remains committed to creating solutions that allow individuals to move freely, live fully, and embrace every stride of life with confidence.
