The Swiss lock with cable pull is used by orthopedic mechanics for orthoses made of carbon fiber or polyethylene (plastic). Without cable pull, the Swiss lock is used for leg orthoses that have been manufactured using the traditional leather-steel technique. This is either a splint-clamp apparatus or a splint-sleeve apparatus. Another form of knee joint lock for such orthoses is the drop lock . The locking bracket is replaced by a metal clip that, when pushed over the joint, locks it. When the metal clamp is pulled up, the joint can move.
