Knee (strike)

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 of a downed opponent. Styles such as Muay Thai and several mixed martial arts organizations allow kneeing depending on the positioning of the fighters.

Straight

The straight knee (also known as a front knee) is a typical knee strike, and involves thrusting the front of the knee into the head or body of an opponent. The straight knee can be applied from a stand-up position both when the combatants are separated, or when they are clinching. A particularly effective clinching position for throwing front knee is the double collar tie, where the head of the opponent is controlled. On the ground, front knees can be effective from a few top positions such as the Side control and north-south position. Typical targets for the front knee include the head, hips, ribs, solar plexus, stomach and thighs. In Muay Thai, a double collar tie with a front knee to the face was traditionally called Hak Kor Aiyara. The groin is widely considered the key target for knee strikes and clinch knee attacks in a street fight according to karate, tae kwon do, muay thai, and many other martial arts.
