Which specialist treats Baker's cyst?

A Baker's cyst is a fluid-filled swelling behind the knee. It can occur when irritation inside the joint increases fluid production, sometimes alongside knee osteoarthritis or a meniscus tear. The clinician will ask when the lump appeared, examine knee movement, and check for tenderness, stiffness, or swelling. Imaging may help distinguish the cyst from other causes of a lump behind the knee.

The cyst itself may be only part of the problem. Treating the underlying joint irritation can reduce pressure and improve movement. A musculoskeletal or sports-medicine physician may also assess the knee, while a physiotherapist can help restore strength and comfortable motion.

Arrange an assessment with an orthopaedic specialist if the swelling persists, limits bending, or returns. Treatment may include activity changes, medicines recommended for you, and an exercise programme. Physiotherapy can address knee strength, flexibility, and movement habits. In selected cases, a clinician may discuss joint aspiration, while surgery is generally considered only when a structural knee problem needs operative treatment.

Until you are assessed, avoid activities that sharply increase pain or pressure behind the knee. Note whether the swelling changes after activity and bring a list of medicines and previous knee injuries to the appointment.

Seek urgent medical assessment for sudden calf swelling or pain, marked warmth or redness, or breathlessness or chest pain. These symptoms can have causes other than a Baker's cyst and should not be attributed to the lump without examination. Arrange routine care for ongoing knee pain or swelling, reduced movement, or a lump that is growing or interfering with walking.

Ask whether the swelling is consistent with a Baker's cyst, what knee problem may be driving it, and whether imaging is needed. You can also ask which activities are suitable, whether physiotherapy or joint aspiration fits your situation, and what changes should prompt an earlier review.
