How long does physiotherapy take to work for Baker's cyst?

Physiotherapy may reduce stiffness and improve knee function over several weeks, but a Baker’s cyst can persist if the knee problem causing fluid build-up remains active. Progress depends on the amount of swelling, knee strength, range of motion and the condition affecting the joint.

Treatment may include gentle movement, quadriceps and hip strengthening, walking advice and ways to reduce activities that repeatedly irritate the knee. Physiotherapy can address function around the swelling, but it does not always remove the cyst itself. Your clinician may need to assess arthritis, meniscus injury or another source of inflammation.

Complete exercises within the advised comfort range and avoid repeated deep squats, kneeling or high-impact activity if these increase pressure behind the knee. Note changes in swelling, knee bending and walking. Do not massage a painful swollen calf until a clinician has assessed it. Read about [Baker's Cyst](/conditions/bakers-cyst/) and [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/).

Seek urgent assessment for sudden calf pain or swelling, warmth, skin colour change, or breathlessness, because a ruptured cyst and a blood clot can feel similar. Arrange review for a locked knee, inability to bear weight, fever, marked redness or rapidly increasing swelling. Tell your clinician if symptoms do not settle with the agreed plan.

Ask what is driving the knee swelling, whether imaging is needed, which exercises are suitable, how to monitor the cyst, and which calf or knee changes require urgent assessment.
