A knee strike (commonly referred to simply as a knee) is a strike with the knee, either with the kneecap or the surrounding area. Kneeing is a disallowed practice in many combat sports, especially to the head, or to any bodypart of a downed opponent. Styles such as Muay Thai and several mixed martial arts organizations allow kneeing depending on the positioning of the fighters. Knee strikes (particularly to the groin for males) are generally agreed to be effective self-defense maneuvers.
