What are the treatments for the condition?

Treatment is not usually needed for the cyst. If symptoms become severe, a needle can be inserted through the skin and into the cyst to drain it. In severe cases, surgery can be used to remove the cyst.

If a cause for the Baker's cyst can be found, the cause may need treatment. For example, a knee injury that causes a cartilage tear may need surgery. A person with rheumatoid arthritis may be given any of a number of medicines to reduce damage to the joints.

What are the side effects of the treatments?

The cyst might come back if fluid is withdrawn from it or after surgery. Surgery may cause bleeding, nerve injury, knee stiffness, and infections. Medicines used for rheumatoid arthritis may cause stomach upset, allergic reactions, and other effects.

What happens after treatment for the condition?

Most people are able to continue or return to normal activities after treatment. Those who have no further symptoms need no further therapy. If symptoms return or continue, further treatment may be advised. Other treatment may be needed for the underlying cause, such as arthritis or knee injury.

How is the condition monitored?

A rapidly growing mass, increased pain, knee or calf swelling, or trouble moving the knee should be reported to the healthcare provider. Any other new or worsening symptoms should also be reported to the doctor.
