Overview
The Knee Knot is a leg entanglement position where the attacker's legs create a complex knot-like configuration around the opponent's knee — a controlling position primarily used for kneebar attacks and as a transitional position within the ashi garami system. [1] The knee knot provides strong control of the opponent's knee joint, preventing them from straightening or bending the leg to escape. [1],[2]

Frequently Asked Questions
What's the key difference between knee shield and Z-guard?
In knee shield, you trap your opponent's leg with a hook. In Z-guard, you position your top shin on top of the opponent's thigh rather than hooking, which allows you to keep your knees separated and connect your feet together by shooting your bottom leg deeper.
Why do I need to keep my knees apart in Z-guard?
Keeping your knees apart by positioning your top shin on the opponent's thigh prevents them from smashing your knees together and weakening your position. With separated knees, you can lock your feet together and defend against mill kicks more effectively.
How do I control my opponent's posture in Z-guard?
Curl your back heel toward your butt with your bottom leg and push your top leg against the opponent's hip to make them sit on their heel. This engaged position makes it very difficult for them to stand up or start passing.
