Inside Hook
Also known as Inside Heel Hook — the canonical term used on this site.
Shortened — inside heel hook
Inside Hook is the shortened name for the inside heel hook — the rotational knee attack in which the attacker rotates the heel inward against the trapped knee.
Etymology. “Inside Hook” drops “heel” from the full name; the abbreviated form predominates in coaching shorthand where context makes the heel-hook category clear.
Mechanics. The inward heel rotation loads the knee against a direction the joint has minimal tolerance for — the structural margin between application and damage is narrow.
Cross-reference. “Inner Heel Hook” and “Inverted Heel Hook” are alternate names. Full mechanical coverage on Inside Heel Hook.
