The 3R80 Prosthetic Knee is a knee prosthesis designed for use by individuals with lower extremity amputation. This knee's rotary hydraulic responds to ground reaction forces during the stance phase of gait. It utilizes a high hydraulic resistance to prevent involuntary flexion of the knee. This stance phase control is advantageous on uneven surfaces, slopes, and when walking down stairs. The knee has four optimized adjustment options for stance phase and swing phase control. Flexion and extension resistance can be adjusted independently. Optimal adjustment values for stance phase damping and sensitivity are achieved by gradually turning the adjustment rings. An extra spring can be integrated into the knee to increase extension assist force. The knee comes with the extra spring, an adjustment tool, and the required tube adapter. CAPACITY: 275 pounds. WEIGHT: 42 ounces.
