When is physiotherapy recommended for baker's cyst?

A Baker's cyst, also called a popliteal cyst, is a fluid-filled swelling behind the knee. It often develops alongside irritation inside the joint, such as arthritis or a meniscus problem. Physiotherapy does not remove the fluid directly, but it can address restricted movement, reduced leg strength and movement habits that aggravate the knee. Assessment helps identify whether the knee can tolerate stretching, strengthening and gradual activity.

A programme may use gentle knee movement, thigh and hip strengthening, balance work, and advice about pacing stairs, squatting and prolonged standing. The therapist may adjust exercises if bending increases pressure behind the knee. Treating the underlying knee problem is often part of the plan, so bring information about locking, clicking, swelling and earlier injuries. Do not massage a painful or rapidly enlarging swelling without medical advice.

Seek prompt medical assessment for sudden calf swelling, warmth, redness or marked tenderness, because these symptoms can resemble a blood clot or a leaking cyst. Get urgent help for chest pain or sudden breathlessness. Contact your clinician if the knee locks, you cannot bear weight, or swelling and pain worsen despite reducing activity.

Ask what is driving the cyst, whether imaging is needed, which exercises are suitable, and what changes should lead you to pause therapy or return for review.
