One of the most common prosthetic devices is the below-knee prosthesis, designed for individuals who have experienced an amputation below the knee.

In this blog post, we will explore the components, benefits, and considerations of a below-knee prosthesis to help you understand how these devices are designed to improve the quality of life.

In this blog, we will explore the components, types, benefits, and considerations when selecting a below-knee prosthesis, shedding light on how it can help improve quality of life and restore the ability to move freely and actively.

What is a Below-Knee Prosthesis?

A below-knee prosthesis is an artificial limb designed for individuals who have lost part or all of their lower leg, specifically below the knee joint. The prosthesis replaces the missing portion of the leg, typically the foot, ankle, and shin, while retaining the natural knee joint. This type of prosthesis helps people walk, run, and perform everyday activities without relying on crutches or wheelchairs.

The design of a below-knee prosthesis is focused on providing stability and natural movement, making it suitable for individuals who want to maintain an active lifestyle, whether in their daily routine or participating in sports. Modern below-knee prostheses are lightweight, durable, and customizable, allowing users to regain mobility and confidence.

The Essential Components of a Below-Knee Prosthesis

A below-knee prosthesis consists of several key components that work together to replicate the function of the natural lower leg. Each part of the prosthesis is custom-made to fit the individual’s residual limb, ensuring comfort, security, and optimal performance. Below are the primary components of a below-knee prosthesis:

1. Socket

The socket is the part of the prosthesis that connects to the residual limb. It is one of the most critical elements in determining the comfort and function of the prosthesis. The socket is custom-molded to fit the unique shape and size of the user’s limb to ensure a secure and snug fit. An ill-fitting socket can cause discomfort, skin irritation, and even sores, which is why working with a skilled prosthetist to achieve the best possible fit is crucial.

To create the socket, prosthetists typically take a mold or 3D scan of the residual limb, and the final socket is crafted from materials such as acrylic or thermoplastic, which provide both durability and flexibility. A well-fitting socket helps distribute weight evenly, reducing pressure points and enhancing comfort.

2. Shank (Pylon)

The shank, also referred to as the pylon, is the structural support of the prosthesis. It connects the socket to the prosthetic foot and helps align the prosthesis with the user’s body. The pylon is made from lightweight but strong materials such as aluminum or carbon fiber, which provide the necessary support while minimizing weight.

The pylon allows the user to walk, stand, and move with stability and balance. It acts as the backbone of the prosthesis, absorbing the forces generated during movement and transmitting them to the foot. Depending on the user’s needs, the pylon may be either fixed or adjustable to accommodate changes in posture and walking style.

3. Foot

The foot of the below-knee prosthesis is designed to replicate the function of a natural foot, providing stability, support, and flexibility. Prosthetic feet come in various types, depending on the user’s activity level and lifestyle.

• Solid Feet: These are basic prosthetic feet made from materials like fiberglass or plastic, providing stability and simplicity at a more affordable price point. While they are not as flexible as advanced prosthetic feet, solid feet are suitable for individuals who need a basic prosthesis for everyday use.
• Energy-Storing Feet: More advanced prosthetic feet are made from materials like carbon fiber, which store and release energy as the user walks. These energy-storing feet provide greater flexibility, a more natural gait, and enhanced shock absorption, making them ideal for active individuals.
• Multi-Axis Feet: These prosthetic feet allow for more natural movement on uneven terrain, providing greater stability when walking on hills or stairs. They feature multiple joints to allow for more fluid motion and adaptability.
• Specialized Feet: For individuals with specific activity needs (e.g., athletes), specialized feet are available, designed for high-impact activities such as running, cycling, or hiking. These feet are lightweight, durable, and optimized for high-performance activities.

4. Knee Joint (If applicable)

In the case of below-knee amputations, the knee joint remains functional, and no additional knee joint is typically required in the prosthesis. However, if the amputee has had an above-knee amputation, the prosthesis will require an artificial knee joint to assist with walking. Below-knee amputees rely on the natural movement of their knee joint to maintain a natural gait and movement.

5. Suspension System

The suspension system is what keeps the socket securely attached to the residual limb. Various types of suspension mechanisms exist, and the choice will depend on the individual’s activity level, limb shape, and comfort preferences. Some common types of suspension systems include:

• Pin Lock Suspension: A pin on the prosthetic socket locks into place with a liner, securing the prosthesis to the limb.
• Vacuum Suspension: A pump creates a vacuum inside the socket, enhancing fit and reducing the risk of the prosthesis shifting during movement.
• Sleeve Suspension: A silicone or elastic sleeve is used to hold the prosthesis securely in place.

Types of Below-Knee Prostheses

Below-knee prostheses come in various types, tailored to meet the user’s specific needs. The design chosen will depend on factors such as activity level, lifestyle, and budget. Here are some of the most common types of below-knee prostheses:

1. Basic Below-Knee Prosthesis

This type of prosthesis is designed for individuals who need a reliable, everyday prosthetic solution. It is typically made from lightweight materials and includes a simple foot design, providing stability and support for regular daily activities. Basic below-knee prostheses are cost-effective and well-suited for people with lower activity levels or those who don’t require advanced features.

2. Energy-Storing Prosthesis

Energy-storing prostheses use advanced materials like carbon fiber to provide energy return during walking or running. The foot component of the prosthesis acts like a spring, storing energy during the step and releasing it during push-off, mimicking the natural function of a foot. This type of prosthesis is suitable for individuals who lead active lifestyles and wish to regain mobility for activities like running, cycling, or hiking.

3. Sports Prosthesis

For individuals who engage in sports, a specialized sports prosthesis is designed to provide maximum mobility and performance. These prostheses are lighter and more flexible, designed to handle the impact and stress of activities like running, jumping, and sprinting. Some sports prostheses come with specialized feet that offer additional shock absorption, while others provide enhanced stability on uneven surfaces or during high-speed movement.

4. Waterproof Prosthesis

Individuals who live near water or engage in water sports may opt for a waterproof below-knee prosthesis. These prostheses are made from waterproof materials and are designed to withstand exposure to water, allowing users to swim or engage in water-based activities without worry. They are often equipped with specialized feet that can handle slippery or submerged surfaces.

The Benefits of a Below-Knee Prosthesis

A well-designed below-knee prosthesis offers numerous benefits, not only improving mobility but also enhancing an individual’s quality of life. Some key benefits include:

1. Restoration of Mobility

   One of the most significant benefits of a below-knee prosthesis is the restoration of mobility. With a properly fitted prosthesis, individuals can walk, stand, climb stairs, and perform everyday activities like cooking, shopping, or driving without the assistance of crutches or a wheelchair.

2. Improved Comfort and Fit

   Modern prosthetics are designed with comfort in mind. With advancements in custom fitting, users can expect a snug and secure fit that minimizes discomfort and skin irritation. A well-designed socket and suspension system reduce the chances of chafing, sores, and blisters, making long-term wear more comfortable.

3. Enhanced Independence and Confidence

   Regaining the ability to move independently is a significant boost to emotional and mental well-being. For individuals who may have felt limited by their amputation, a prosthesis allows them to regain confidence in themselves, participate in family and social activities, and re-enter the workforce.

4. Active Lifestyle

   With the right prosthesis, users can engage in more than just basic walking. Advanced below-knee prostheses are designed for running, hiking, or even playing sports, allowing individuals to maintain an active lifestyle and participate in the activities they enjoy.

5. Improved Stability and Balance

   Prostheses are designed to mimic the natural gait and balance of a person’s leg. This helps prevent falls and provides stability while walking, climbing stairs, or navigating uneven terrain. For individuals who have lost their limb, this stability is crucial to prevent further injuries.

Considerations When Choosing a Below-Knee Prosthesis

Selecting the right below-knee prosthesis requires careful consideration of various factors. Some essential considerations include:

1. Lifestyle Needs and Activity Level

   The prosthesis you choose should match your daily activities and lifestyle. For instance, if you are highly active and enjoy running or playing sports, an energy-storing or sports prosthesis would be ideal. Conversely, if you need a prosthesis for more everyday tasks, a basic prosthesis may be sufficient.

2. Fit and Comfort

   The fit of the socket is paramount to comfort and usability. An ill-fitting socket can cause discomfort and lead to skin issues or even permanent damage. Ensure that you work with a skilled prosthetist who can create a custom socket tailored to your limb shape.

3. Material Durability

   The materials used in the prosthesis—such as carbon fiber, titanium, or aluminum—will determine the prosthetic’s weight, strength, and flexibility. While lightweight materials offer more comfort, it is essential to balance durability and performance.

4. Budget

   Prosthetic limbs can be costly, and some advanced prostheses may require more investment due to specialized features. However, it’s important to consider long-term benefits and how the prosthesis can improve your mobility and quality of life. Always discuss options with your prosthetist to find a solution that fits your budget.

5. Maintenance and Adjustments

   A prosthesis requires regular maintenance and occasional adjustments to ensure it continues to perform well. Regular follow-up appointments with your prosthetist are necessary to monitor the fit and condition of the prosthesis and make any required modifications.
