Description
A Knee-Ankle-Foot Orthosis, commonly known as KAFO, is a type of orthopedic brace used to provide support and stability to the knee, ankle, and foot. It is typically prescribed for individuals with various neuromuscular or musculoskeletal conditions that affect their lower limbs. KAFOs are custom-made devices designed to assist with walking, improve posture, and prevent further injury or deformity.
The primary components of a KAFO include:
Knee Joint: The knee joint in a KAFO is an adjustable hinge that allows controlled bending and extension of the knee. It may include locks or stops to prevent unwanted movement, depending on the patient’s specific needs.
Ankle Joint: The ankle joint is designed to provide stability and control motion at the ankle. It may be a simple hinge or a more complex design that allows some degree of controlled movement.
Footplate: The footplate is the part of the orthosis that supports the foot and provides a surface for weight-bearing and walking.
Uprights: The uprights are the vertical bars that connect the knee joint to the ankle joint and stabilize the orthosis around the leg.
Straps and Padding: KAFOs are secured to the leg using straps and padded liners. These help to distribute pressure and improve comfort during use.
KAFOs are prescribed for a variety of conditions, such as:
Spinal cord injuries: KAFOs can provide support and stability for individuals with paralysis or weakness in the lower limbs due to spinal cord injuries.
Cerebral palsy: People with cerebral palsy may benefit from KAFOs to improve their gait and posture.
Muscular dystrophy: KAFOs can help individuals with muscle weakness caused by conditions like muscular dystrophy.
Post-polio syndrome: For those experiencing late effects of polio, KAFOs may be used to assist with walking.
Severe fractures or ligamentous injuries: KAFOs can aid in stabilizing and protecting the knee and ankle during the healing process.
It’s important to note that KAFOs are custom-made and must be prescribed and fitted by a trained orthotist or prosthetist. Proper fitting and regular follow-up with the healthcare provider are essential to ensure that the orthosis provides the intended benefits and fits comfortably.
