Lower Limb Orthotics

KAFO Leg Brace — Knee Ankle Foot Orthosis Solutions & Technologies

A KAFO (Knee Ankle Foot Orthosis), also called a long leg brace, is a custom-made full-leg orthosis designed to help individuals with significant lower-limb weakness or paralysis walk and stand safely. Modern KAFO technology has evolved dramatically — from traditional drop lock braces to advanced microprocessor-controlled stance control systems.

A KAFO stabilises the knee, ankle and foot. Different mechanisms are available based on the patient’s muscle strength and anatomical needs — including drop lock (locked knee), stance control and microprocessor systems. Every brace is custom-made considering the user’s lifestyle and clinical condition.

By System Type

Types of KAFO Leg Braces

Three main KAFO systems address different clinical needs, each balancing durability, function and walking style. The right brace is determined by an orthotist based on a full biomechanical evaluation.

Carbon fiber KAFO leg brace
Carbon Fiber

Carbon Fiber KAFO

The ideal choice for users seeking lightweight construction with high durability. The energy storage and return property reduces walking effort, allowing more natural gait mechanics throughout the day.
  • Exceptional lightweight, high strength
  • Energy storage & return during gait
  • Slim, discreet profile under clothing
  • Best for active and dynamic users
Drop lock KAFO with locked knee mechanism
Drop Lock

Drop Lock KAFO (Locked Knee)

The traditional, reliable choice when knee control is completely lost. The manual locking mechanism provides maximum stability during standing and walking — widely used for polio survivors and complete paralysis cases.
  • Ideal for complete loss of knee control
  • Maximum stability and safety
  • Easy to use, simple maintenance
  • Proven, time-tested mechanism
Electronic microprocessor stance control KAFO
Microprocessor

Electronic Stance Control KAFO

Microprocessor-controlled joints (such as the Otto Bock C-Brace and E-MAG Active) deliver gait closest to natural walking. Sensors detect step speed and ground conditions, locking and unlocking the knee dynamically.
  • Microprocessor-controlled knee joint
  • Real-time step & terrain detection
  • Minimises stumbling and fall risk
  • Top-tier KAFO technology

Medical Conditions

Who Needs a KAFO Leg Brace?

A KAFO is prescribed for individuals with significant muscle weakness or paralysis in the lower limbs. It plays a key role in rehabilitation for neurological and orthopaedic conditions, helping patients regain the ability to stand and walk safely.

Post-Polio Syndrome

Polio survivors with residual muscle weakness and joint instability benefit from KAFO support — historically the most common indication for long leg braces worldwide.

Spinal Cord Injury (Paraplegia)

For patients with paraplegia or paresis following spinal cord injury, KAFO leg braces help restore independent ambulation capacity during rehabilitation.

Muscular Dystrophy

A KAFO supports knee and ankle stability in progressive muscle diseases, slowing functional decline and preserving the ability to walk for as long as possible.

Stroke & Cerebral Palsy

Post-stroke hemiplegia and cerebral palsy with significant lower-limb weakness benefit from KAFO bracing to improve gait safety and reduce knee buckling.

Traumatic Knee Instability

KAFOs provide functional support for knee and ankle instability resulting from accidents or major injuries, helping patients return to walking sooner.

Multiple Sclerosis & Neuromuscular Disease

Patients with multiple sclerosis, transverse myelitis and similar neuromuscular conditions benefit from KAFO support to maintain mobility and independence.

Why It Matters

Why a Custom KAFO Design?

Every patient’s body structure, muscle control level and lifestyle is unique. Off-the-shelf solutions are not enough for a successful KAFO outcome — custom fitting is the foundation of safe, comfortable, long-term use.

01

Biomechanical Gait Analysis

Precise measurement and biomechanical assessment — including 3D scanning and gait analysis — form the foundation of an effective KAFO design.
02

Material Selection

The right material is chosen based on the user’s lifestyle and activity level: carbon fiber for active users, polypropylene for entry-level needs, or hybrid combinations.
03

Follow-up & Technical Support

Regular check-ups and ongoing technical support after delivery are essential for long-term success — including socket adjustments and joint maintenance.

Pricing Information

How Much Does a KAFO Leg Brace Cost?

KAFO pricing is determined individually based on the system type, materials and your clinical needs. Below is a general guide to help you understand the price ranges.

Price range

$2,000  to  $75,000

The final price depends on the KAFO system type, materials selected (carbon fiber, polypropylene, metal), joint mechanism (drop lock, stance control, microprocessor) and your individual clinical condition. A standard polypropylene drop lock KAFO sits at the lower end, while a microprocessor-controlled electronic KAFO (such as Otto Bock C-Brace) sits at the higher end.

Entry

Standard drop lock KAFO

from $2,000

Mid-range

Carbon fiber KAFO

$5,000 – $15,000

Premium

Electronic stance control

up to $75,000

KAFO (Knee-Ankle-Foot Orthosis) Frequently Asked Questions

A KAFO (Knee Ankle Foot Orthosis), also known as a long leg brace, is a custom-made full-leg orthosis that supports and stabilises the knee, ankle and foot. It is prescribed for individuals with significant muscle weakness or paralysis — such as polio survivors, spinal cord injury patients and those with muscular dystrophy — to enable safe standing and walking.
KAFO leg braces are commonly prescribed for post-polio syndrome, spinal cord injury (paraplegia and paresis), muscular dystrophy, traumatic knee and ankle instability, cerebral palsy and stroke-related lower-limb weakness. They are also used for multiple sclerosis and other neuromuscular conditions.
A carbon fiber KAFO is lightweight, durable and provides energy return during walking — ideal for active users. A drop lock (locked knee) KAFO uses a manual locking mechanism to fully stabilise the knee, making it the preferred choice when knee control is completely lost. The right system is determined by a specialist based on a clinical evaluation.
An electronic stance control KAFO (such as the Otto Bock C-Brace or E-MAG Active) uses microprocessor-controlled knee joints and sensors to detect step speed and ground conditions in real time. The knee locks during stance phase for stability and unlocks during swing phase for a natural gait, minimising the risk of stumbling.
>KAFO leg brace prices range from $2,000 for a standard polypropylene drop lock KAFO to $75,000 or more for an advanced microprocessor electronic KAFO. Carbon fiber KAFOs sit in the mid-range, typically $5,000 to $15,000. For a personalised quote, contact us on WhatsApp.
Yes. Pediatric KAFO systems are designed and adjusted according to the child’s growth. Due to growth rate, pediatric leg braces are renewed more frequently than adult ones — typically every 1 to 2 years depending on the child’s development.
Custom KAFO leg braces are typically delivered within 2 to 4 weeks after the initial measurement and biomechanical assessment. Electronic stance control KAFO systems may take slightly longer due to programming and calibration.
Adaptation time varies based on the brace type and the patient’s clinical condition. Physiotherapy support significantly accelerates the process. Our clinic provides technical support throughout the entire adaptation period — including socket adjustments and gait training.
