Hiza-gatame (ground)
This ground variation of Ude-hishigi-hiza-gatame uses the knee as the fulcrum while both judoka are in ne-waza. Tori immobilizes Uke's shoulder and wrist, aligns the elbow against the knee, and extends the arm gradually without dropping weight onto the joint.

Movement sequence
- From a stable ground position, isolate Uke's arm and keep the shoulder from rotating.
- Place the inside of your knee precisely beneath or against the elbow while controlling the wrist with both hands.
- Remove space and extend the arm slowly across the knee, stopping immediately at the tap.
- Apply only under qualified supervision, increase pressure gradually, and release immediately when Uke taps.
