Baker cyst

Baker's Cyst or Popliteal Cyst is a type of fluid-filled cyst that develops at the back of the knee, often due to certain knee conditions such as arthritis or meniscus tear. It was named after the British surgeon, William Morrant Baker, who first described it.

Causes

The primary cause of a Baker's Cyst is damage to the knee joint. This damage can be due to a variety of conditions, including osteoarthritis, rheumatoid arthritis, gout, and meniscus tear. These conditions can lead to an overproduction of synovial fluid, which can accumulate and form a cyst.

Symptoms

The symptoms of a Baker's Cyst can vary depending on the size of the cyst. Some people may not experience any symptoms, while others may feel pain or stiffness in the knee, or a sensation of tightness or fullness at the back of the knee. In some cases, the cyst may burst, causing pain and swelling in the calf.

Diagnosis

A Baker's Cyst is typically diagnosed through a physical examination and medical history. Imaging tests such as an MRI scan or ultrasound may also be used to confirm the diagnosis and rule out other conditions.

Treatment

Treatment for a Baker's Cyst typically involves addressing the underlying knee condition. This may include physical therapy, medication, or in some cases, surgery. In some cases, the cyst may be drained using a needle in a procedure known as aspiration.
