Alternate — reverse-direction heel hook
Reverse Heel Hook is the alternate name for the inside heel hook — using “reverse” to flag the inward-rotation direction as the inverse of the outside heel hook’s outward rotation.
Etymology. “Reverse” specifies the directional inversion relative to the outside heel hook; the label is one of several confusable names alongside “inverted heel hook,” “inner heel hook,” and “inside hook.” Precise vocabulary uses “inside heel hook” to avoid the directional-naming ambiguity.
Mechanics. The inward heel rotation loads the knee in its most vulnerable axis — the structural margin under rotation is narrow and pain arrives only after the danger zone is reached.
Cross-reference. “Inside Hook,” “Inner Heel Hook,” and “Inverted Heel Hook” are alternate names. Full mechanical coverage on Inside Heel Hook.
