What is Baker’s Cyst (Popliteal Cyst)?

A Baker’s cyst is a fluid-filled cyst that causes a bulge and a feeling of tightness behind your knee. A Baker’s cyst, also called a popliteal cyst, is usually the result of a problem with your knee joint, such as arthritis or a cartilage tear. Both conditions can cause your knee to produce too much fluid, which can lead to a Baker’s cyst.
