Types of above-the-knee prosthetic limbs are essential medical solutions designed to enhance the quality of life for individuals who have lost a limb due to accidents or health conditions. In this article, we will examine in detail the types of above-the-knee prosthetic limbs, outlining the benefits of each, their cost ranges, and practical guidance on selecting the most suitable option.
When is one type of above-the-knee prosthesis indicated?
Types of above-the-knee prosthetic limbs are a vital solution for individuals who have lost a limb due to traumatic incidents, such as car crashes or workplace injuries, or medical conditions like diabetes or cancer. Choosing the right prosthesis depends on several key factors, including:
- Amputation level: Types of above-the-knee prosthetic limbs are designed for individuals whose amputation is above the knee joint. These prostheses require a personalized design to match the user’s anatomy and functional needs.
- General health status: Chronic conditions such as heart disease or diabetes can influence the suitability of certain types of above-the-knee prosthetic limbs. People with heart conditions or diabetes may need a thorough evaluation and consultation with specialists before making any decision.
- Lifestyle: A person’s lifestyle plays a key role in choosing the right prosthesis. Factors like physical activity level, occupational demands, and recreational interests, such as sports, help determine which type of above-the-knee prosthetic limb best supports their daily functions and mobility goals.
What is the difference between above-the-knee and below-the-knee prosthetic limbs?
Above-the-knee and below-the-knee prosthetics differ in design and function, which greatly affects the user experience. Here are some key differences:
- Design: All types of above-the-knee prosthetic limbs incorporate a prosthetic joint that mimics the movement of the knee, allowing for a greater range of motion, while below-knee prostheses focus on restoring lower leg motion only. This difference in design means that above-knee prostheses require more complex and sophisticated techniques.
- Comfort: All types of above-the-knee prosthetic limbs may be more comfortable than below-the-knee prostheses but require more qualification. Limbs should be tailored to the shape of the leg and body weight, which helps minimize pressure on certain areas and reduces the risk of skin issues.
- Ability to perform: Above-the-knee limbs provide a greater ability to perform daily activities such as walking, climbing stairs, and running, and may enhance a person’s ability to participate in social and athletic activities, contributing to a better quality of life.
Types of above-the-knee prosthetic limbs
There are different types of above-the-knee prosthetic limbs, each with distinct characteristics. Here are the most common types:
- Hydraulic limbs: Hydraulic limbs rely on the use of hydraulic systems to achieve better movement and control. These systems rely on fluid pressure to provide the user with great strength and support. We will mention the most important features of hydraulic limbs
- It allows for flexible adjustment of speed and movement to suit the user’s needs
- It provides smooth and natural movement, enhancing performance in activities like walking and running
- It helps improve athletic performance
- It offers a more natural user experience
- However, hydraulic prosthetics may be more complex to maintain and require technical expertise for proper operation
- Bionic (smart) limbs: Bionic limbs use advanced technologies such as sensors and software to optimize the user experience. Features of bionic limbs include:
- It uses artificial intelligence to analyze body movements
- It adjusts the movement according to the user’s needs
- It provides the user with precise control over movement and is highly adaptable to various activities, thereby improving performance
- However, electronic prosthetics can be more expensive and require batteries and regular maintenance, and some users may find it challenging to adapt to the new technology
- Limbs made from carbon or synthetic fibers: Carbon limbs use advanced materials such as carbon and synthetic fibers in the manufacturing process. These limbs feature
- Lightweight
- Highly durable, allowing for easier movement and reducing fatigue
- Provides greater comfort and stability for the user, making it suitable for everyday use
- Resistant to corrosion and has a long lifespan
- However, carbon fiber prosthetics may be less flexible than hydraulic or electronic ones, which could affect performance in certain sports activities
- Advanced fused limbs: There are advanced types of above-the-knee prosthetic limbs that combine features of the previous types
- These devices are hybrid systems that combine hydraulic technology with robust construction, providing users with smooth and effortless movement
- They may be made from advanced materials such as carbon fiber, reinforced with electronic components
- They offer a high level of performance and control, along with greater comfort and stability for the user
- However, they are also the most expensive compared to other types
Which type of above-the-knee prosthetic limb is right for you?
When choosing a type of above-the-knee prosthetic limb, there are several important factors to consider:
- Activity level: If you are active or play sports regularly, you may need a prosthesis that can give you more flexibility, as it is important to think about the activities you would like to do after the prosthesis is fitted.
- Comfort: The limb should be comfortable throughout the day, so it’s important to try them on before making a final decision. It should fit the shape of the leg and be lightweight. Consulting with specialists can help determine if the limb is suitable.
- Cost: Prices vary widely between types of above-the-knee prosthetic limbs, so it’s important to determine your budget. Prices can range from several thousand to tens of thousands of dollars, depending on the type and technology. The budget should also include future maintenance costs.
Challenges users may face after installation
Users may face some challenges after prosthetic installation, such as:
- Problems with the skin: Constant pressure from the prosthesis can lead to sores or infections. It is important to maintain a clean area and wear the prosthesis correctly to prevent issues. Users should see a doctor if there are any signs of irritation.
- Acclimatization of movement: It may take some time to acclimatize to the new limb, which requires patience and constant training from the user. Physical rehabilitation sessions are essential for helping users learn how to control their movements properly.
- Ongoing costs: Prosthetics may require periodic maintenance or replacement, which can increase costs. Users should be prepared to bear these additional costs, including spare parts and maintenance costs.
Physical rehabilitation after installing a type of above-knee prosthesis
Physical rehabilitation is an essential part of the prosthetic adaptation process. Users should perform specific exercises to enhance strength and flexibility, such as:
- Leg strengthening exercises: To strengthen the muscles around the amputation site to help improve stability and support, these exercises can include lifting weights or using exercise machines.
- Balance exercises: To improve the ability to stand and move with confidence, which reduces the risk of falling, these exercises can include standing on one foot or using balance tools.
- Walking exercises: Such as walking on different surfaces and gradually increasing distances to facilitate the process of acclimatization to the new limb.
Cost of different types of above-the-knee prosthetic limbs in Turkey
The cost of different types of above-the-knee prosthetic limbs varies from one another due to the different degrees of complexity among them and the different prices of the materials involved in their manufacture. Here are some approximate prices for each type:
| Type of prosthesis | Approximate Price (USD) | Description |
|---|---|---|
| Hydraulic limbs | 15,000 – 35,000 | Utilizes advanced hydraulic technology. Prices vary based on quality and additional features. |
