What is a Baker’s cyst (and how physio can help)?
A Baker’s cyst — also called a popliteal cyst — is a fluid-filled swelling behind the knee. It commonly develops when excess joint fluid is pushed into a pouch at the back of the knee, often linked to arthritis, meniscus tears or knee inflammation.
Symptoms can include a visible/firm lump behind the knee, tightness, stiffness, aching or difficulty bending the knee.
Sometimes pain increases with activity; rarely the cyst can rupture and cause sudden calf pain and swelling.
How Warners Bay Physiotherapy can help:
-Assessment: thorough knee exam to identify underlying causes (joint mechanics, muscle strength, movement patterns).
-Pain and swelling control: manual therapy, taping, compression and guided activity modification.
-Strength and stability: tailored exercises to strengthen quadriceps, hamstrings, hip and calf muscles to unload the knee and reduce fluid production.
-Mobility and load management: restore knee range of motion and correct movement patterns to reduce joint irritation.
-Education: advice on activity progression, footwear, pacing and self-management strategies (ice, compression, safe exercise).
-Coordinate care: liaise with your GP or orthopaedic team if imaging, injection or referral is needed.
When to see us:
If you have swelling or pain behind the knee, limited bending, or recurring symptoms that affect daily life or sport, book an assessment. Early physio can reduce symptoms and address the root cause.
