ارتزهای زانو-مچ-پا (KAFO) و لگن-KAFO (HKAFO)

When the quadriceps cannot hold the knee, patients lock it by hand or adopt compensations that cause back pain and fatigue. A KAFO transfers knee control to the brace frame.

A simple drop-lock knee is robust and suits limited walking. A stance-control knee is a major step forward: the knee stays stable in stance but releases in swing, giving a near-natural gait at much lower energy cost.

For low-level paraplegia, an HKAFO adds a hip joint and pelvic band to control abduction–adduction and rotation, used with crutches or a walker.

We weigh stability against weight carefully: the more a frame controls, the heavier it is, so the choice must track each person's real mobility goals.
