What are Knee Ankle Foot Orthoses?
Knee Ankle Foot Orthoses (KAFOs) are specially engineered orthotic devices designed to support and stabilise the knee, ankle, and foot. They are typically used for individuals with significant weakness or instability in these areas, offering structural support to enhance mobility and functional ability.
Structure and Function of KAFOs
KAFOs can be constructed from various materials such as carbon composites, plastic, metal, and leather. The knee joint options available for KAFOs are vast but can be broadly categorised into non-locking, locking, and stance control types. Your orthotist will evaluate your specific condition and functional needs to recommend the most suitable knee joint for your needs. Typical components may include:
- Knee Joint: Provides stability and controls knee movement.
- Ankle Joint: Supports the ankle, preventing excessive movement.
- Foot Plate: Stabilises the foot, maintaining proper alignment.

Examples of Pathologies Benefiting from KAFOs
- Poliomyelitis: KAFOs provide essential support for weakened muscles and joints, improving mobility and stability.
- Spinal Cord Injury: Individuals with lower limb paralysis benefit from the structural support and stabilisation offered by KAFOs.
- Muscular Dystrophy: KAFOs help manage progressive muscle weakness, maintaining mobility for as long as possible.
- Multiple Sclerosis: KAFOs stabilise the lower limbs, aiding those with significant muscle weakness and spasticity.
- Post-Stroke: For individuals with hemiplegia or severe muscle weakness, KAFOs provide necessary support for walking and balance.
Value of KAFOs in Orthotic Intervention
Enhanced Mobility
- Support for Weak Muscles: KAFOs provide critical support for individuals with muscle weakness, enabling them to walk more efficiently and safely.
- Improved Gait: By stabilising the knee and ankle, KAFOs help correct abnormal gait patterns, making walking more natural and less tiring.
Increased Stability and Safety
- Fall Prevention: stabilising the lower extremities reduces the risk of falls, especially in individuals with significant instability.
- Joint Protection: KAFOs protect joints from excessive movement and potential injuries, preserving long-term joint health.
Pain Reduction
- Pressure Redistribution: Custom KAFOs help redistribute pressure, reducing pain and discomfort in the lower limbs.
- Joint Alignment: Proper alignment provided by KAFOs reduces abnormal joint loading, alleviating pain associated with misalignment
Prevention of Deformities
- Corrective Support: KAFOs help prevent the development or progression of deformities caused by muscle imbalances or neurological conditions.
- Contracture Prevention: By maintaining proper joint positions, KAFOs prevent muscle shortening and joint stiffness.
Enhanced Quality of Life
- Increased Independence: Improved mobility and stability enable individuals to perform daily activities more independently.
- Psychological Benefits: Greater mobility and independence can improve mental health, self-esteem, and overall well-being.
