Reverse ashi knee lock escape
Also known as Aoki Lock Escape — the canonical term used on this site.
Descriptive — knee lock from a reversed ashi rotation
Reverse ashi knee lock escape is the descriptive name for Aoki lock defence, naming the entanglement rotation that produces it rather than the competitor it is named after.
Etymology. “Reverse ashi” marks the configuration: the attacker’s rotation runs opposite to a standard ashi garami, which is what puts the medial knee under load. Naming the rotation is more useful defensively than naming the lock, because the rotation is what a defender can see coming.
Mechanics. There is no grip to fight — the lock is produced by leg configuration alone — so squaring the hips against the reverse rotation is the defence. Straightening the leg and extracting it follows; contesting hands achieves nothing because no hands are involved.
Cross-reference. “Medial knee compression defence” is the anatomical name. Full escape coverage on Aoki Lock Escape.
