Overview on Baker’s cyst

A Baker’s cyst is defined as an unusual swelling in the bursa positioned behind the knee joint. It is not fully known what causes the cyst, but it might form if the lining of the knee joint releases excess fluid after an injury or in certain types of arthritis. In addition, it can occur if the meniscus is torn.

What are the signs?

In most cases, a Baker’s cyst can trigger the following:

  • Knee pain, typically in the back region
  • Swelling
  • Sensation of fullness in the site behind the knee

The doctor will assess the knee and discover a protrusion in the rear part of the joint. An MRI or ultrasound might be taken to provide the doctor details if a cyst is present.

Management of Baker’s cyst

Apply an ice pack or pack of frozen vegetables that has been wrapped with a clean towel or cloth on the site every 3-4 hours for 20 minutes at each application.

Oftentimes, the cyst will settle on its own. In case the cyst does not trigger any undesirable symptoms, it does not require treatment.

If treatment is necessary, it involves the following:

  • Apply an ice pack or pack of frozen vegetables that has been wrapped with a clean towel or cloth on the site every 3-4 hours for 20 minutes at each application.
  • Elevate the affected knee on a cushion or pillow while sitting or lying down.
  • Use an elastic bandage or sleeve around the knee.
  • An anti-inflammatory medication can be taken as instructed by the doctor.
  • In some cases, the cyst might require drainage or surgery is carried out for the removal of the cyst.
