A leglock is a joint lock that is directed at joints of the leg such as the ankle, knee or hip joint. A leglock which is directed at joints in the foot is sometimes referred to as a foot lock and a lock at the hip as a hip lock. Leglocks are featured combat sports and martial arts such as Sambo, Brazilian Jiu-Jitsu, catch wrestling, mixed martial arts, Shootwrestling and submission wrestling, but are banned in some sports featuring joint locks such as judo.
Leglocks are considered more difficult techniques to apply effectively than armlocks, since the legs are generally stronger limbs than the arms. Leglocks require full body leverage to be effective since they attack large joints, such as the knee. Compared to armlocks, leglocks usually require more intricate positions than the mount, sidecontrol or guard, and are often considered to be risky because of the possibility of losing position.
In training or sparring, leglocks are applied in a slow and controlled manner, and are often not hyperextended such as in the case of the comparatively dangerous heel hook. Instead, submission is signalled before the lock is fully applied. In self-defense application, or when applied improperly or with excessive force, leglocks can cause muscle, tendon and ligament damage, even dislocation or bone fractures.
