Abstract: An additively manufactured ankle-foot orthosis. The ankle-foot orthosis includes an additively manufactured footplate and a calf cuff separate from the additively manufactured footplate. A pre-fabricated strut connects the additively manufactured footplate to the additively manufactured calf cuff and includes thickness and width adapted to define a patient-specific stiffness about an ankle joint of a patient. The stiffness of the pre-fabricated strut is suited to one or more of a gait need or a gait requirement of each patient, and the additively manufactured footplate has a portion with a shape complementary to a shape of a portion of the pre-fabricated strut. So configured, a collective shape and volume of the additively manufactured footplate and the pre-fabricated strut together are adapted to fit inside a shoe of the patient.
