Baker’s cyst
Alternative Names
Popliteal cystTreatment
Often no treatment is necessary and the practitioner can observe the cyst over time. If the cyst is painful, treatment is usually aimed at correcting the underlying problem, such as arthritis or a meniscus tear. Remove the cyst is generally not done because it may damage nearby blood vessels and nerves.
Sometimes, a cyst can be drained (aspirated), if the fluid inside it has become solid and gel-like.
Outlook (Prognosis)
A Baker's cyst is a benign lesion that will not cause any long-term harm, but can be annoying and painful. Long-term disability is very rare, as most cases improve with time or arthroscopic surgery.
Possible Complications
Complications are unusual, but may include:
- Long-term pain and swelling
- Complications from associated injuries, like meniscal tears
When to Contact a Medical Professional
Call for an appointment with your health care provider if there is a swelling behind the knee that becomes large or painful. Pain could be a sign of infection, which is not normally associated with Baker's cyst.
