About Above Knee Prosthetics

Above knee prosthetics, also known as transfemoral prosthetics, are designed for people who have undergone an amputation above the knee joint. This type of prosthesis is planned to reestablish both functionality and appearance, significantly improving the user's mobility and quality of life.

Types of Above Knee Prosthetics

1. Basic Above Knee Prosthesis
   • Designed for stability and ease of use.
   • Ideal for patients with lower activity levels.
   • Simpler construction with fewer components.
2. Advanced Above Knee Prosthesis
   • Incorporates more sophisticated components for enhanced mobility.
   • Suitable for active individuals.
   • May include hydraulic or pneumatic knee joints for smoother and more natural motion.
3. Microprocessor-Controlled Knees
   • Uses advanced technology for real-time adjustments and precise control.
   • Provides a more natural gait pattern.
   • Ideal for highly active users and those needing fine-tuned control.

Process of Fitting an Above Knee Prosthesis

1. Initial Assessment
   • Detailed evaluation of the residual limb’s condition.
   • Assessment of the patient’s activity level and specific requirements.
2. Casting and Measurement
   • Accurate measurements of the residual limb are taken.
   • A cast or digital scan is created to design a custom socket.
3. Prosthetic Fabrication
   • Custom socket is crafted based on the cast or scan.
   • Selection of suitable knee joint and foot components.
4. Initial Fitting
   • Prosthesis is fitted to the patient for the first time.
   • Adjustments are made to ensure comfort and correct alignment.
5. Gait Training
   • Physical therapy sessions to help the patient adapt to the new prosthesis.
   • Training on walking, standing, and moving with the prosthetic limb.
6. Follow-Up and Adjustments
   • Regular follow-up appointments to monitor progress.
   • Additional adjustments are made as necessary for optimal performance.

Benefits of Above Knee Prosthetics

1. Enhanced Mobility
   • Provides better balance and stability compared to higher level amputations.
   • Allows for a more natural gait pattern with the help of advanced knee joints.
2. Improved Comfort
   • Custom-fit sockets ensure comfort and minimize skin irritation.
   • Advanced suspension systems enhance overall fit and comfort.
3. Increased Activity Levels
   • Suitable for a range of activity levels, from basic daily activities to high-performance sports.
   • Microprocessor-controlled knees offer precise adjustments for various activities and environments.
4. Aesthetic Appeal
   • Prosthetics can be designed to closely match the appearance of the natural limb.
   • Options for cosmetic covers to enhance the prosthesis’s appearance.

Conclusion

Above knee prosthetics are an important solution for people who have undergone a transfemoral amputation. With advancements in prosthetic technology, these devices offer improved mobility, comfort, and aesthetic appeal. Whether you need a basic prosthesis for everyday activities or an advanced microprocessor-controlled knee for high-level performance, there are options available to meet your specific needs. The fitting process, from initial assessment to regular adjustments, ensures that you receive a prosthesis that is both functional and comfortable, helping you regain independence and enhance your quality of life.
