This type of KAFO is used to provide hip and knee support. They generally have locking knee joints and have an ischial seat for weight-bearing, thus accommodating weakness in the hip abductor muscles.
This device is commonly used for: polio, Trendelenburg gait, neural-tube defect and arthrogryposis. Arthrogryposis is a disorder characterized by multiple congenital joint contractures with weakness in the hip and knee extensors. Children who present with arthrogryposis commonly have clubfoot (equinovarus foot) and plantar flexor muscle weakness.
