SIDE KNEE

The side knee is an oblique-angle knee strike that travels diagonally rather than straight up or directly across. Thrown from clinch range, it slips between the opponent's frame and lands on the ribs, floating ribs, or kidney area at an angle that body posture alone cannot fully shield. The side knee is particularly effective against opponents who frame straight forearms across the chest to defend the straight knee — the angled path goes around their frame rather than into it. Mechanically, the side knee uses a slight hip tilt and lateral knee drive rather than the vertical thrust of the straight knee. The lead foot stays planted; the knee rises and turns inward at the same time, contacting with the corner of the kneecap on the soft tissue between the opponent's ribs and the iliac crest. Body weight transfers through the hip on the kicking side, not just the knee itself. The side knee is a common follow-up after the straight knee fails to land cleanly — when the opponent frames against the first strike, the second one finds the seam.
