What is a Popliteal Cyst?
------------------------------------------------------------------------------
QUESTION: A bulging mass at the back of my knee, that keeps growing and is
now quite tender, has been named as a "popliteal cyst". While that may give
it a name, it stills leaves me with lots of anxiety and desire to know more
about this problem. Will you please tell me what a popliteal cyst is and what
type of treatment are available?
------------------------------------------------------------------------------
ANSWER: Popliteal cysts are painful fluid-filled sacs which form where joints
come together. Cysts of this type most frequently occur behind the knee (in
the "popliteal" area"), but are also found in other areas where there are
freely moveable joints such as the bend of the arm, shoulder, hip and neck.
Usually associated with either joint-destroying diseases (such as
arthritis and gout) or injury to the affected area, popliteal cysts are caused
when the protective covering around a joint spills out into the space between
the tear and the surface skin. In a way it's like a giant blister, only it
doesn't go away so easily.
Unlike a blister which eventually dries up, popliteal cysts grow hard and
tough, sometimes blocking off the flow of liquid in or out. In many cases,
cortisone injected into the joint--along with rest--will reduce the pain and
swelling and lead to a successful cure. However, if the cyst can not be
reduced by this method or is very large, surgery may be required.
