Above Knee Prosthesis (AK) — Transfemoral Prosthetic Leg Solutions in Gwalior, India
An Above Knee Prosthesis (AK / Transfemoral Prosthesis) is a prosthetic leg for individuals with amputation above the knee joint. It is one of the most complex prosthetic challenges, requiring a prosthetic knee joint, pylon, socket, and foot working together to provide stable, controlled walking.
At Limbgenixx, Gwalior, we fit above-knee prosthetics ranging from basic mechanical systems for older patients to advanced Ottobock microprocessor-controlled knees (C-Leg, Genium) for active users. Our prosthetists perform comprehensive gait analysis and provide structured rehabilitation programs. We serve patients from across Madhya Pradesh, UP, Rajasthan, and pan-India.
Types of Above Knee Prosthesis
Mechanical / Polycentric Knee AK
Single-axis or polycentric knee joints for stable, reliable walking. Cost-effective and suitable for low-to-moderate activity amputees — the most widely prescribed AK system in India.
Hydraulic Knee Prosthesis
Hydraulic knee joints provide smooth, speed-adaptive movement. Better for active users who walk on varied terrain — offers superior stance and swing phase control compared to mechanical knees.
Pneumatic Knee Prosthesis
Nitrogen-filled pneumatic knees deliver responsive swing control. Lightweight and suitable for moderate-activity patients who require a balance of cost and performance.
Microprocessor Knee (Ottobock C-Leg)
The Ottobock C-Leg microprocessor knee uses real-time sensors to adapt to every step. Highest safety, most natural gait — for active amputees who demand the best prosthetic knee technology available.
What an Above-Knee Prosthesis Is Made Of
A transfemoral limb carries one component a below-knee limb does not: a prosthetic knee. That addition changes how the whole limb is specified, because the knee has to be stable when you put weight through it and free to swing when you do not.
| Part | What it does |
|---|---|
| Socket | Custom shell taking load through the pelvis and thigh soft tissue |
| Liner and suspension | Interface against the skin and whatever holds the limb on |
| Knee unit | Provides stance stability and controls swing. See prosthetic knee joints |
| Pylon and adapters | Connect the assembly and set alignment |
| Foot | Ground contact and energy return. See prosthetic feet |
Alignment matters more above the knee than below it. Small changes in how the knee sits relative to the hip and foot change how readily the knee stays stable at heel strike, which is why fitting takes longer and involves more walking.
Socket Designs and Suspension
Socket designs
The quadrilateral socket is the older four-sided design, loading through the ischial tuberosity sitting on a defined shelf. Ischial containment designs enclose part of the pelvis instead, which can give better control of the limb in side-to-side movement.
Which suits you depends on limb length, soft-tissue bulk, pelvic shape and how much walking you do. Both are still fitted; neither is simply obsolete.
Suspension
- Suction — a valve expels air so the socket holds directly. Close coupling, and needs stable limb volume.
- Pin or lanyard with a liner — mechanical attachment, easier to don and judge.
- Silesian belt or pelvic band — an external strap, used where additional security or rotational control is needed.
A note on sitting. Above-knee users spend a lot of the day seated, and a socket that works beautifully standing can be uncomfortable sitting. Tell us how much of your day is spent sitting — it genuinely affects the design.
Choosing a Knee: Matching the Unit to How You Move
Knee units are usually matched to functional level — how much walking you do, how varied your surfaces are, and whether you need to vary your speed. The internationally used K-level framework describes this:
| Level | Typical mobility | Knee characteristics usually considered |
|---|---|---|
| K1 | Transfers and level walking at a fixed slow pace | Maximum stance stability; locking or weight-activated units |
| K2 | Limited community walking, some kerbs and uneven ground | Stability-biased polycentric units |
| K3 | Community walking at varying speed | Pneumatic or hydraulic swing control |
| K4 | High activity, children, active adults, sport | Higher-demand units. See sports prosthetics |
Two things worth saying plainly. A more advanced knee is not automatically better — it may be heavier, more fragile and harder to service, and a sophisticated knee cannot compensate for a socket that does not fit. And functional level is not fixed: people frequently move up a level as confidence grows, which is one reason components are chosen so they can be changed later.

Frequently Asked Questions
An above-knee (AK) prosthesis is an artificial limb for people with transfemoral (above-knee) amputation. It includes a prosthetic knee joint, pylon, and foot — all controlled by the user's thigh muscles and body weight.
A BK prosthesis is simpler — it replaces only the lower leg. An AK prosthesis is more complex, requiring an artificial knee joint plus foot. AK amputees require more rehabilitation time and energy to walk than BK amputees.
Above-knee prosthesis cost in India ranges from Rs. 40,000 for a basic mechanical knee to Rs. 8,00,000+ for Ottobock microprocessor C-Leg systems. Contact Limbgenixx for detailed pricing and financing options.
The Ottobock C-Leg 4 and Genium X3 are considered the best microprocessor knees globally. For budget-conscious patients, hydraulic knees offer an excellent balance. Limbgenixx recommends based on your activity level and goals.
Most AK amputees need 3–6 months of physiotherapy and prosthetic gait training to walk confidently. Limbgenixx provides in-house rehabilitation sessions and connects patients with physiotherapists in Gwalior.
