The meat cut classification 사태 refers to both the front and back legs of the cow.
There are further Korean meat cut classifications that go into detail about the uses and textures of different sections of the front and back legs.
I followed a Korean cut classification that aligns with how these meat cuts are organized in Korean standards. Some cuts of meat may be next to or near the main classification but still be considered to fall under that category.
Korea uses over 100 meat cut classifications. Some meat cuts that fall under this cut are the following:
Fore Shank/ Front Shank (앞사태 / ap-ssa-tae)

Location On Animal: This cut is located below the 앞다리 on the front legs of the cow.
