An ankle lock which is also called shin lock is a leg lock applied to ankle joints. According to professional grappling and martial arts information, an ankle lock is hyper-extension of the talocrural joint through plantar hyperflexion. Ankle lock is applied in such a way that the joint is compressed in the process rather performance of applying. It is also effective in straining muscle. The technique specially allows the term to be used is straight ankle lock. It is totally dependent on the performing style that it is known to us with different names. In that perspective it is known as Achilles lock.

Ankle lock technique uses legs to isolate the opponent’s legs. Then the attacker uses his armpit to grab or place the foot in it. By moving the hips forward, the foot becomes insanely flexed. It creates a strong and effective joint lock on the ankle. The forearm serves as a point of joint lock in the whole movement, and may cause severe pressure on the Achilles tendon. This straight ankle lock is quite often referred to as an "Achilles lock". Thus the widely used art in this technique is Achilles lock. Another stylized technique used in ankle locks is the Quasimodo Shin Lock which is not common. Brazilian jiu-jitsu allows these techniques to be used.
