A Baker's Cyst is a well defined sac of fluid that arises in the back of the knee. This type of cyst is also know as a popliteal cyst due to its location in the popliteal area (backside) of the knee. These cysts contain knee joint fluid that has been forced out of its encapsulation. This article explains why these cysts form and the medical symptoms you want to be aware of.
Baker's Cyst
The most noticeable symptom is a visible mass that can be seen as a bulge in the back of the knee. This bulge will be most easily seen when the person is standing with the knee fully extended This mass will be able to be felt and will generally feel soft and may be tender or painful. Some persons will experience an ache or tightness around the knee while others will experience no discomfort.
Baker's cysts are fairly common and may result due to an injury to the back of the knee or may be associated with an underlying condition such as arthritis or gout. Some cysts may occur without a known cause.
The initial diagnosis of a Baker's cyst will come from the afflicted person as they will likely observation the cyst protruding from the back of their knee. This condition should be evaluated by a physician. The evaluation may include a physical examination, radiological testing (i.e. x-ray, ultrasound, arthrogram or MRI scan) and possibly blood and/or a urine tests depending on the suspected cause.
If the cyst is associated with an underlying condition, treatment will be focused on that condition. If the cyst is painful or is interfering with activity, surgical removal may be necessary. Baker's Cysts typically resolve when the protruding fluid is removed. Joint aspiration or cortisone injections may be necessary.
