Bakers Cyst or Popliteal cyst is a localized swelling at the back of the knee. It is usually caused by an injury or condition in the knee joint which will make the back of the knee swell up increasing pressure and causing pain.
There may be a painless or painful swelling behind the knee. The cyst may feel like a water-filled balloon. Sometimes, the cyst may break open (rupture), causing pain, swelling, and bruising on the back of the knee and calf. It is important to know whether pain or swelling is caused by a Baker's cyst or a blood clot. A blood clot (deep venous thrombosis) can also cause pain, swelling, and bruising on the back of the knee and calf. A blood clot may be dangerous and requires immediate medical attention.
