Hiza juji gatame escape

Hiza juji gatame escape is the judo-derived name for the defence against the kneebar — the leg-lock submission that loads the knee joint by hyperextending it against the natural range of the leg.

Etymology. Hiza (膝) means “knee”; juji (十字) means “cross” or “the character ten,” referring to the perpendicular geometry of the bodies at the finish; gatame (固め) means “hold.” The combined term — knee cross-hold — is the judo parallel to the upper-body juji gatame (armbar) applied to the leg instead of the arm. The technique appears in Kodokan judo’s kansetsu-waza (joint-lock) catalogue and remains in the legacy judo vocabulary; in modern no-gi grappling and BJJ, the technique is more commonly named “kneebar” or “straight kneebar.” The escape term carries the parent technique’s name forward in judo and judo-influenced submission curricula.

Mechanics. The escape’s priority is removing the hyperextension load from the knee before the joint reaches structural failure. The defending player must either clear the entanglement that connects the leg to the attacker’s hips or rotate the knee inward — both require disrupting the inside-space connection the attacker depends on for the hyperextending pull.

Cross-reference. English-speaking no-gi uses “kneebar escape” or “straight kneebar defence.” Full mechanical coverage on Kneebar Escape.
