Ottobock 3R78 Pneumatic Knee Joint

The 3R78 knee joint is lightweight yet robust and offers high stance phase safety for users with moderate activity levels. The joint geometry effectively shortens the prosthesis when your leg swings through, giving you more ground clearance. A large flexion angle of 150° also provides greater freedom of movement. The knee joint also supports you when walking at various speeds and is approved for a body weight of up to 100 kilograms.

Product Description

Ottobock 3R78 Pneumatic Knee Joint
Lightweight Pneumatic Control for Smooth & Energy-Efficient Walking

The Ottobock 3R78 Pneumatic Knee Joint is a lightweight pneumatic prosthetic knee designed to deliver smooth, responsive, and energy-efficient gait control for above-knee (AK) and transfemoral amputees with low to moderate activity levels. Built with Ottobock’s proven pneumatic technology, the 3R78 automatically adapts swing resistance to changes in walking speed, enabling a more natural cadence and comfortable everyday mobility.

The pneumatic swing phase control system allows the knee to respond dynamically to faster or slower walking without the need for frequent manual adjustments. This results in consistent toe clearance, reduced hip effort, and improved gait symmetry, making the 3R78 particularly suitable for community ambulation and rehabilitation. Its predictable behavior supports confidence during walking while maintaining simplicity and ease of use.

Designed with a focus on lightweight construction and reliability, the Ottobock 3R78 reduces overall prosthesis weight, helping lower energy expenditure and fatigue during prolonged use. The knee can be fine-tuned by clinicians to match the user’s body weight, strength, and functional goals, making it suitable as a rehabilitation prosthetic knee, preparatory or temporary prosthetic knee joint, and in many cases as a definitive prosthetic knee for daily walking.

At Credence Prosthetic India, the Ottobock 3R78 Pneumatic Knee Joint is fitted through a patient-specific clinical protocol, including functional assessment, precise alignment, customized socket integration, and structured gait training. Credence’s experienced prosthetists ensure optimal pneumatic tuning and follow-up support, helping amputees achieve smoother walking, reduced fatigue, and long-term comfort in real-world conditions.
