Baker's Cyst

This bulge, also called a "popliteal cyst," forms behind the knee. It's a swollen bursa. A bursa is a fluid-filled sac that helps reduce friction between soft tissues and bones. There are several of these sacs in the knee and in other joints. A swollen bursa can be uncomfortable, or even painful. A Baker's cyst is often called a "sentinel sign" of other problems in the knee joint. Our doctors are experts in helping diagnose such conditions and treating your injury.
