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.
A tear to the cartilage-like meniscus can also result in pain in the back of the knee, depending upon what sort of tear occurs. Pain and swelling behind the knee is common with a meniscus tear; the severity of the pain and whether the stability of the knee is compromised depends upon the extent of the tear. This pain behind the knee when itâs bent will often intensify during a deep knee flex or when getting up after sitting.
