A Baker\u2019s cyst is a fluid-filled sac that causes swelling, fullness, and a feeling of tightness behind your knee. The pain may worsen when you fully bend or extend your knee, or during physical activity.<\/span><\/p>\n<\/div>\n

Baker\u2019s cyst usually develops after issues such as knee osteoarthritis or cartilage wear. These conditions can lead to the overproduction of joint fluid, which accumulates behind the knee and forms a cyst.<\/span><\/p>\n<\/div>\n

It is one of the most common causes of pain behind the knee. In many cases, when the underlying condition is treated, the Baker\u2019s cyst also disappears.<\/span><\/p>\n<\/div>\n

What Is a Baker\u2019s Cyst?<\/strong><\/span><\/h2>\n<\/div>\n
<\/div>\n
\n

A Baker\u2019s cyst is a fluid-filled sac located at the back of the knee joint. It typically forms when excess joint fluid pushes out into the popliteal space. The cyst is usually soft, movable, and painless \u2014 but as it grows, it may restrict movement and cause a feeling of tightness.<\/span><\/p>\n<\/div>\n

A Baker\u2019s cyst is not a disease on its own; it is usually a sign of an underlying knee problem. Meniscus tears, osteoarthritis, rheumatoid arthritis, or trauma can increase joint fluid production, leading to cyst formation. It becomes more noticeable during activities such as squatting or climbing stairs.<\/span><\/p>\n<\/div>\n

According to scientific studies, Baker\u2019s cysts are seen in 10\u201340% of patients with intra-articular knee conditions. A 2020 study published in Clinical Rheumatology<\/em>\u00a0found that 45% of patients with rheumatoid arthritis had Baker\u2019s cysts detectable by ultrasound. <\/span><\/p>\n<\/div>\n

The study also suggested that these cysts may indicate synovial inflammation \u2014 a crucial clue for diagnosis and treatment planning.<\/span><\/p>\n<\/div>\n
