Understanding Above Knee Prosthetics

Artificial limbs designed for higher-level amputations provide unique solutions to restore movement and independence. These devices combine advanced engineering with personalized fittings to meet diverse mobility needs.

What Are Above Knee Prosthetics?

These devices consist of five essential parts working together:

Socket: Custom-molded from laminated or thermoplastic materials for precise fit⁷
Knee systems: Microprocessor-controlled units like Ottobock’s C-Leg adapt to walking speeds⁸
Suspension: Uses vacuum or sleeve suction to secure the device⁸
Shank: Lightweight carbon fiber or titanium pylon connects components⁷
Foot-ankle assembly: Energy-returning designs mimic natural movement⁹

How Do They Differ from Other Prosthetics?

Compared to below-knee solutions, these devices require different approaches:

Feature	Above-Knee	Below-Knee
Energy Use	60% more effort required	More efficient movement
Control	Requires hip muscles	Uses ankle motion
Weight Distribution	Focuses on pelvic stability	Balanced through shin

Advanced models like the Linx prosthesis integrate sensors and multiple resistance settings for varied activities⁷. Rehabilitation typically takes longer due to the mechanical complexity of knee joints⁹.

Exoskeletal designs offer durability, while endoskeletal versions allow easier adjustments as needs change. The right choice depends on activity levels and personal preferences.

Common Causes of Above Knee Amputation

Limb loss can result from various medical conditions and accidents, each requiring specialized care. Early awareness helps manage risks and improve outcomes.

Peripheral Vascular Disease

Peripheral vascular disease causes 54% of surgical amputations by restricting blood flow, leading to tissue death¹⁰. This disease often affects smokers and those with high cholesterol.

Trauma and Accidents

Traumatic injuries—like car crashes or machinery accidents—account for 45% of cases¹⁰. In children, 75–80% result from trauma, with traffic accidents being the top cause¹¹.

Diabetes-Related Complications

Diabetes causes 54% of amputations due to non-healing ulcers and infections¹⁰. Poor circulation and nerve damage increase risk.

Cause	Percentage	Key Risks
Peripheral Vascular Disease	54%	Tissue death, restricted flow
Trauma	45%	Emergency surgery, long rehab
Diabetes	54%	Ulcers, infections

“Managing blood sugar and quitting smoking cut amputation risks by 50%.”

Post-surgery, patients face risks like infection or phantom limb pain¹⁰. Proper wound care and therapy are critical.

Components of Above Knee Prosthetics

Every prosthetic limb is built with precision-engineered parts that work together for seamless movement. These components adapt to walking speeds, terrains, and activity levels for personalized use¹².

FAQ

What are the main differences between above knee and below knee prosthetics?

Above knee prosthetics replace the entire leg, including the knee joint, requiring more advanced components for stability and movement. Below knee options retain the natural joint, making gait training easier.

How long does rehabilitation take after receiving an above knee prosthetic?

Rehabilitation typically lasts 3–6 months, depending on factors like muscle strength, balance, and adherence to physical therapy. Consistent practice improves mobility over time.

Can peripheral vascular disease affect prosthetic use?

Yes. Poor circulation may slow healing or increase discomfort. Working with a prosthetist ensures proper socket fit and reduces skin breakdown risks.

What types of knee joints are available for prosthetics?

Options include mechanical (single-axis or polycentric) for basic stability and computerized knees with adaptive resistance for smoother movement on varied terrain.

How do I manage phantom limb pain after surgery?

Techniques like massage, mirror therapy, and medications help. Early physical therapy also reduces pain by promoting nerve adaptation.

Are there sports designed for above knee amputees?

Absolutely. Adaptive sports like wheelchair basketball, swimming, and seated volleyball allow participation without stressing the residual limb.

What should I look for when choosing a prosthetic leg?

Prioritize comfort, activity level, and suspension type. A certified prosthetist can recommend systems like suction sockets or locking liners based on your needs.

How often should I replace my prosthetic components?

Lifespan varies—knee systems last 3–5 years, while sockets may need adjustments sooner due to residual limb changes. Regular check-ups ensure optimal function.
