One of the more common causes of pain in the back of the knee joint, specifically, is a popliteal synovial cyst, which is also known as a bakerâs cyst. This fluid-filled cyst at the back of the leg often forms in response to arthritis or other cartilage damage. The bulge creates a feeling of tightness behind the knee as well as stiffness and swelling and pain behind the knee and calf. For many, this pain intensifies when flexing or fully extending the leg.
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.
