What is the Popliteus?
The popliteus is a small but important muscle located at the back of your knee. It sits deep, meaning it’s underneath larger muscles, and it runs from the outer part of your thigh bone down to the back of your shin bone. Even though it’s small, it plays an outsized role in keeping your knee moving smoothly and feeling stable, especially during walking, running, squatting, lunging, and changing direction.
