Popliteal cyst

What is Popliteal cyst?

A Baker's cyst, also known as a popliteal cyst, is a benign swelling of the semimembranosus or more rarely some other synovial bursa found behind the knee joint. It is named after the surgeon who first described it, William Morrant Baker (1838–1896). This is not a "true" cyst, as an open communication with the synovial sac is often maintained.
