Össur Navii Prosthetic Knee

Product Overview

Designed for daily walking, the Össur Navii Prosthetic Knee is a microprocessor-controlled prosthetic knee that boosts user confidence by improving stability and adaptability. It continuously analyzes movement patterns and adjusts resistance in real time to support smoother transitions between stance and swing phases.

Navii is typically recommended for K2–K3 users who benefit from enhanced stance control and stumble recovery. Its sensor-driven system responds dynamically to changes in walking speed, direction, and terrain, helping reduce fall risk and improve overall gait symmetry.

The knee’s compact design supports system integration with a variety of prosthetic feet and socket configurations. By automatically adjusting hydraulic resistance, Navii provides consistent performance during level walking, slopes, and uneven ground.

Features and Benefits

• Microprocessor-controlled stance phase: Increases stability during weight-bearing.
• Real-time adaptive resistance: Adjusts to speed changes and terrain variations.
• Stumble recovery support: Enhances safety during unexpected disturbances.
• Smooth swing control: Promotes consistent step timing and leg advancement.
• Compact mechanical profile: Allows for streamlined prosthetic build.
• Slope and ramp adaptation: Improves control on inclines and declines.
• Rechargeable system: Supports daily use with routine charging.

With sensor-driven resistance and real-time adjustments, Navii promotes controlled movement and improved gait stability throughout the day.
