Is it true that is ham hock the same as bacon hock based on the following text?

A ham hock (or hough) or pork knuckle is the joint between the tibia/fibula and the metatarsals of the foot of a pig, where the foot was attached to the hog's leg. It is the portion of the leg that is neither part of the ham proper nor the ankle or foot (trotter), but rather the extreme shank end of the leg bone.
