In cases affecting the knee-joint the sinews can be extended by the same means as I have described for the thigh. And when it has slipped out backwards, as described above, a round ball of some kind is placed on the ham, and when the leg is bent up over it, the knee slips back again. In the other cases it is to be replaced by the surgeon's hands while the bones are being drawn apart in opposite directions.

If the ankle is dislocated forwards, the broad sinew behind is hard and tense, and in those cases manipulation is required; if backwards, the heel is almost hidden and the sole is elongated.
