Many of hapkido's joint control techniques are said to be derived largely from [[Daitō-ryū Aiki-jūjutsu]]. They are taught similarly to [[Aikido]] and [[Ju Jutsu]] techniques, but in general the circles are smaller and the techniques are applied in a more linear fashion. Hapkido's joint manipulation techniques attack both large joints (such as the elbow, shoulder, neck, back, knee, and hip) and small joints (such as wrists, fingers, ankles, toes, and jaw).

Most techniques involve applying force in the direction that a joint moves naturally and then forcing it to overextend or by forcing a joint to move in a direction that goes against its natural range of motion. These techniques can be used to cause pain and force a submission, to gain control of an opponent for 'come along' techniques (as is often employed in law enforcement), to assist in a hard or gentle throw or to cause the dislocation or breaking of the joint. Hapkido differs from some post-war styles of Aikido in its preservation of a great many techniques which are applied against the joint that were deemed by some{{Who|date=May 2014}} to be inconsistent with Aikido's more pacifistic philosophy.

; Wristlocks
Hapkido is well known for its use of a wide variety of [[wristlock]]s. These techniques are derived from Daitō-ryū Aiki-jūjutsu although their manner of performance is not always identical to that of the parent art. Still many of the techniques found in hapkido are quite similar to those of Daito-ryu and of Aikido, which was derived from that art. Examples of such techniques are: the supinating wristlock, pronating wristlock, internal rotational wristlock, and the utilization of pressure points on the wrist. These techniques are common to many forms of Japanese Jujutsu, Chinese [[Chin Na|chin na]], and even "catch as catch can" wrestling.

; Elbowlocks
Although well known for its wristlocking techniques, Hapkido has an equally wide array of tactics which center upon the manipulation of the elbow joint (see [[armlock]]). The first self-defense technique typically taught in many hapkido schools is the ''knife-hand elbow press''. This technique is thought to be derived from Daitō-ryū's ''ippondori'', a method of disarming and destroying the elbow joint of a sword-wielding opponent. Hapkido typically introduces this technique off a wrist-grabbing attack where the defender makes a circular movement with his hands to free himself from the opponent's grasp and applies a pronating wristlock while cutting down upon the elbow joint with their forearm, taking their opponent down to the ground, where an elbow lock is applied with one's hand or knee to immobilize the attacker in a pin. Both Daito-ryu and Aikido prefer to use hand pressure on the elbow throughout the technique rather than using the forearm as a "hand blade ({{Korean|hangul=수도|hanja=手刀}})", cutting into the elbow joint, in the Hapkido manner.
