A KAFO is a Knee Ankle Foot Orthotic. This device extends from the thigh to the foot and is generally used to control instabilities in the lower limb by maintaining alignment and controlling motion. Instabilities can be either due to skeletal problems: broken bones, arthritic joints, bowleg, knock-knee, knee hyperextension or muscular weakness and paralysis. There are many different reasons to use a KAFO and there are many different designs. Each design has its own special features and its own specific way to be put on properly. At Sunshine P&O, the orthotist will customize it to your specific needs and will show you the proper way to put it on.
