- Kao Dode (Jumping knee strike) - the Thai boxer jumps up on one leg and strikes with that leg's knee.

- Kao Loi (Flying knee strike) - the Thai boxer takes step(s), jumps forward and off one leg and strikes with that leg's knee.

- Kao Tone (Straight knee strike) - the Thai boxer simply thrusts it forward (not upwards, unless he is holding an opponents head down in a clinch and intend to knee upwards into the face). According to one written source, this technique is somewhat more recent than Kao Dode or Kao Loi.Supposedly, when the Thai boxers fought with rope-bound hands rather than the modern boxing gloves, this particular technique was subject to potentially vicious cutting, slicing and sawing by an alert opponent who would block it or deflect it with the sharp "rope-glove" edges which are sometimes dipped in water to make the rope much stronger. This explanation also holds true for some of the following knee strikes below as well.

The clinch version of this move was scientifically proven recently to be the strongest blow using the legs in martial arts. The test subject delivered the strike to a high-tech dummy. On a person the blow would have fragmented the ribs, caused two inches of chest compression, and caused severe internal bleeding in the organs.

- Kao Noi (Small knee strike) - the Thai boxer hits the inside upper thigh (above the knee) of the opponent when clinching. This technique is used to wear down the opponent or to counter the opponent's knee strike or kick.
