Baker's cysts usually go away without requiring any treatment. However, in certain cases doctors may deal with the condition by treating the underlying cause or draining the fluid within the cyst using a syringe. A baker's cyst does not cause any long term harm regardless of cause, according to the National Institutes of Health in the United States.
A baker's cyst is characterized by a swelling behind the knee. The cyst is made up of a fluid that normally lubricates the knee joint. The main cases of this condition include rheumatoid arthritis, knee arthritis, tearing of the meniscal cartilage of the knee, injury and other complications to the knee joint.
In certain situations, the cyst may break open and the fluid will spill. When the cyst breaks open, some people may experience pain while others may feel nothing. If the cyst is caused by a condition such as arthritis, the doctor will simply treat the arthritis in order to get rid of the cyst.
If the cyst is brought about by injury, it is likely to disappear over time. This means no medical treatment is necessary. However, if the affected person experiences pain, the doctor may drain the fluid by the use of a needle and syringe. Use of a walker, resting the knee joint, taking painkillers and maintaining a healthy weight are some of the things to keep in mind when experiencing this condition.
