Synovial fluid provides lubrication and protection for the knee joint while it moves. When an injury or damage to the knee joint occurs, it is possible for synovial fluid to leak and create a fluid-filled sac behind the knee known as a Baker’s cyst. If you have a Baker’s cyst, treatment is available from our orthopedic physicians at DOCS Health in Los Angeles.

Causes and Symptoms of Baker’s Cysts

A Baker’s cyst is also called a popliteal cyst, or popliteal synovial cyst. Individuals of all ages can experience a Baker’s cyst, but it is more common in older people. Injuries to the knee or diseases that impact the structure of the knee can cause a Baker’s cyst to form in the space behind the knee. Various types of arthritis in the knee, like osteoarthritis and rheumatoid arthritis, can result in a higher risk for Baker’s cysts.

There are often limited symptoms with a Baker’s cyst. Many people with a Baker’s cyst do not have any symptoms at all. If symptoms are present, they can include:

  • Knee stiffness
  • Pain behind the knee
  • Swelling when the knee is straightened

If you experience symptoms from a Baker’s cyst, treatment is available. The first course of action may be treating the contributing factors, such as arthritis. Other possible treatments can include conservative treatments of ice, rest or over-the-counter pain medicines. Steroid injections can also relieve the discomfort of a Baker’s cyst. Many Baker’s cysts will dissipate without treatment, but in severe cases, the cyst may need to be surgically removed.
