Baker's Cyst Physiotherapy
Physiotherapy support for knee pain and swelling presentations associated with Baker's cyst symptoms.
A Baker's cyst is a collection of fluid behind the knee, often associated with irritation inside the joint. Physiotherapy may help the accompanying stiffness, strength and walking difficulties; it does not directly drain a cyst. A new unexplained lump should be checked by a GP before being treated as a routine knee problem.
This guide is general information and does not replace a clinical assessment.
When to get urgent help
Sudden worsening leg pain or swelling, warmth or skin-colour change needs an urgent GP assessment or NHS 111 advice: a ruptured cyst and a blood clot can look similar. If leg pain or swelling occurs with chest pain or breathlessness, call 999 or go to A&E. Do not wait for a physiotherapy appointment.

Assessment
Discuss any GP diagnosis, previous knee injury, arthritis and changes in swelling.
Check whether sudden calf symptoms require urgent assessment for a clot or ruptured cyst.
Assess knee bending, straightening and muscle strength within a comfortable range.
Review how swelling affects walking, stairs and the activities you want to regain.
Treatment
Address movement and strength difficulties alongside management of the underlying knee condition.
Select gentle knee exercises without forcing painful bending against the swelling.
Adjust walking and standing demands, then rebuild activity as symptoms allow.
Recommend medical review for an uncertain diagnosis, persistent swelling or worsening symptoms.
Aftercare & self-management
At your appointment, agree which exercises to do, how often to practise them and when to review your progress.
Reduce activities that increase swelling rather than repeatedly testing the knee's limits.
Rest with your leg supported and elevated if that helps the swelling.
Follow your agreed movement plan; do not try to squeeze or drain the lump.
Seek urgent medical help for sudden calf pain, warmth, redness or worsening swelling.

Frequently Asked Questions
Can physiotherapy remove a Baker's cyst directly?+
No. Physiotherapy may help associated knee stiffness, strength and function, but it does not drain or remove the cyst. A new unexplained lump should be checked by a GP, and persistent or changing swelling may need further medical assessment.
Is exercise safe with a Baker's cyst?+
Gentle rehabilitation may be suitable after assessment, without forcing painful knee bending. Sudden calf pain or swelling needs urgent medical advice because a ruptured cyst and a blood clot can cause similar symptoms.
Do cyst symptoms always need aspiration?+
Not always. Management depends on severity, cause, and functional impact.
