Behind-the-back knee bar
Also known as Lateral Knee Bar — the canonical term used on this site.
Training background: Descriptive alternative — attacker behind the opponent
Descriptive — behind-the-back kneebar entry
Behind-the-back knee bar is the descriptive name for the lat knee bar — flagging the behind-the-back entry geometry that produces the lateral attack angle.
Etymology. “Behind-the-back” specifies the attacker’s body position relative to the opponent’s leg; “knee bar” attaches the submission category. The compound predominates in instructional vocabulary that emphasises the entry-and-position context.
Mechanics. The behind-the-back configuration positions the attacker to load the knee laterally — the angle differs from front-facing kneebar entries.
Cross-reference. “Lateral knee bar” and “Rear kneebar” are alternate names. Full mechanical coverage on Lat Knee Bar.
