C-Leg 4

Product Overview

The Ottobock C-Leg 4 represents the gold standard in microprocessor knee technology. This advanced prosthetic solution continuously adapts to your unique walking patterns in real time, providing unprecedented stability and natural movement across various terrains and activities.

Designed for individuals with knee disarticulation, transfemoral amputation, or hip disarticulation in mobility grades 2-4, the C-Leg 4 supports users throughout the entire gait cycle with intelligent sensor technology that responds instantaneously to changes in direction, speed, and environment.

With its enhanced IP68 waterproof rating, improved stance phase control, and intuitive smartphone app functionality, the C-Leg 4 allows users to navigate daily challenges with confidence - whether descending stairs step-over-step, walking backward safely, or moving through uneven terrain.

Available in two stylish colors (Desert Pearl and Midnight Shadow) and supporting users up to 300 pounds, this proven microprocessor knee system empowers wearers to focus on living life to the fullest rather than thinking about every step.

Features and Benefits

• IP68 Waterproof Rating: Enhanced protection allows submersion in freshwater up to 3 meters for 1 hour, providing significantly improved durability for daily activities in various weather conditions.
• Stumble Recovery Plus: Always-active fall protection that automatically detects potential stumbles during the swing phase and instantly activates resistance to maintain balance and prevent falls.
• Manual Locking Function: Secure the knee in full extension with a simple tapping pattern, even when using a cosmetic cover, providing stability for activities requiring extended standing.
• Improved Stance Release: Enhanced support for descending ramps and stairs with smoother transitions when taking short or quick steps, increasing confidence on varied terrain.
• Intelligent Sitting Support: Detects sitting motion and provides controlled resistance that mirrors your speed, then switches to a comfortable free-swinging joint when seated
• Choice Between Stance Functions: Select intuitive stance (automatically detects standing needs) or deliberate stance (requires more conscious control) based on personal preference.
• MyMode Plus Customization: Configure two activity-specific settings from an expanded selection of options, easily activated via smartphone app or personalized movement pattern.
• User-Friendly Cockpit App: Control settings, check battery status, switch between modes, and perform self-tests via an intuitive application compatible with both iOS and Android devices.
• Training Function: Provides feedback signals after successful swing phase initiation to support gait training and help troubleshoot movement patterns during adaptation.
• Deep Sleep Mode: Conserve battery during extended periods without access to charging, ideal for long trips, outdoor activities, or travel to areas with limited power access.
• Redesigned Charger: One-handed operation makes charging easier and more convenient, with an additional USB charging adapter available for flexible power options.
• Customizable Appearance: Personalize the prosthesis with durable, protective shield covers that add style while protecting against environmental factors and wear.
• Safe Backward Walking: Confidently move in reverse without compromising stability, providing greater flexibility in tight spaces or social situations.
• Verified Clinical Benefits: Extensive studies confirm that the C-Leg reduces falls by up to 64% compared to non-microprocessor knees while decreasing compensatory movements and cognitive effort.
