Losing a leg above the knee (transfemoral amputation) can be life-changing, but modern prosthetic technology allows people to regain independence, mobility, and confidence. One of the most important decisions when selecting an above-knee prosthesis is choosing the right prosthetic knee joint.
In Sri Lanka, several advanced knee joint options are available, ranging from affordable mechanical knees to intelligent microprocessor-controlled knees. The best choice depends on your lifestyle, activity level, age, occupation, and budget.
This guide explains the different types of prosthetic knee joints and helps you choose the most suitable option.
Unlike a below-knee prosthesis, an above-knee prosthesis must replace both the knee and lower leg. The prosthetic knee controls:
A properly selected knee joint can significantly improve quality of life.

Microprocessor knees use sensors and computer technology to monitor walking hundreds of times per second.
Although these knees are more expensive, they provide the highest level of mobility and safety.
The “best” knee depends on individual needs.
| Lifestyle | Recommended Knee |
|---|---|
| Elderly | Mechanical Knee |
| Low Activity | Mechanical or Polycentric |
| Moderate Activity | Hydraulic Knee |
| Active Worker | Hydraulic or Microprocessor Knee |
| Sports & Outdoor Activities | Microprocessor Knee |
| Frequent Walking | Hydraulic or Microprocessor |
A prosthetist will evaluate:
Choosing the right knee ensures better comfort and long-term success.
Modern knee joints can provide:
Professional prosthetic assessment includes:
Working with a qualified prosthetist ensures the prosthesis is customized to your individual needs.
Microprocessor knees generally offer the highest level of safety because they continuously adjust resistance and can help reduce the risk of stumbling and falls.
Mechanical knees are often the most durable and require minimal maintenance. Hydraulic and microprocessor knees also have long service lives when maintained according to the manufacturer’s recommendations.
For active users who walk frequently, work outdoors, or need greater stability, a microprocessor knee can significantly improve mobility, confidence, and quality of life.
Yes. Many users begin with a mechanical knee and upgrade to a hydraulic or microprocessor knee as their activity level or budget changes.
The best above-knee prosthetic knee joint is the one that matches your mobility goals, lifestyle, and budget. Whether you choose a reliable mechanical knee, a versatile hydraulic knee, or an advanced microprocessor knee, professional assessment and fitting are essential for achieving the best outcome.
If you are in Sri Lanka and need an above-knee prosthesis, consult a qualified prosthetist for a comprehensive evaluation and personalized recommendation.
