Ferrari KAFO with Knee Lock

It is used for example with MMC children with L4 lesion level, when quadriceps function is insufficient. There are several options for the knee joint. The ankle joint can have free or restricted motion. The above knee part is posterior. The structure of the orthosis is made of thermal plastic with metal and/or composite reinforcements. With MMC children the lower extremities can be joined with a waist belt in order to compensate the inactivity of extensors, abductors and outward rotators. If hamstrings are tight, a knee cuff is added to straighten the knee.
