Ottobock 3R106 Modular Knee Joint

The key element of the new 3R106 Pro is the servo-pneumatic control. Its powerful dual-chamber pneumatic unit with progressive damping properties has a flexion valve that the O&P professional sets for the user’s normal walking speed. At faster walking speeds, the flexion resistance increases auto-adaptively, which prevents excessive flexion of the knee joint. As a result, pendulum movements in the swing phase are smoothly controlled, even at higher walking speeds. The integrated, automatic quick venting of the flexion chamber ensures that smooth extension movement is possible even at higher walking speeds – so a greater range of walking speeds is supported.

Product Description

Ottobock 3R106 Modular Knee Joint
Reliable Mechanical Polycentric Knee for Safe & Functional Mobility

The Ottobock 3R106 Modular Knee Joint is a robust mechanical polycentric prosthetic knee designed to provide high stance stability, controlled gait, and long-term durability for above-knee (AK) and transfemoral amputees. Built on Ottobock’s proven engineering standards, the 3R106 knee is especially suitable for users who prioritize safety, reliability, and predictable knee behavior during everyday walking and rehabilitation.

Featuring a polycentric (four-bar linkage) design, the 3R106 knee offers enhanced stance phase security, significantly reducing the risk of knee buckling during early stance, downhill walking, and uneven surfaces. The polycentric geometry also improves toe clearance during swing phase, enabling smoother leg advancement and reducing compensatory hip movements. This makes the knee particularly beneficial for users with shorter residual limbs or those requiring added confidence during weight bearing.

The Ottobock 3R106 Modular Knee Joint incorporates a durable friction-based swing phase control system that can be adjusted by clinicians to match the user’s walking speed, body weight, and functional ability. Its mechanical simplicity ensures consistent performance, minimal maintenance, and high load tolerance, making it a dependable option for long-term use. The knee is commonly prescribed for rehabilitation prosthetic use, preparatory or temporary prostheses, and in many cases as a definitive prosthetic knee for low to moderate activity users.

At Credence Prosthetic India, the Ottobock 3R106 knee is fitted using a comprehensive clinical protocol that includes detailed patient assessment, precise alignment, customized socket integration, and structured gait training. Credence’s experienced prosthetists ensure that the knee’s polycentric behavior and swing resistance are optimally tuned, helping reduce energy expenditure, improve walking efficiency, and support long-term musculoskeletal health. With ongoing follow-up and fine-tuning, Credence Prosthetic India ensures dependable outcomes for amputee rehabilitation and daily mobility.
