What is Baker’s Cyst?
A Baker’s cyst (or popliteal cyst) is a
fluid-filled swelling that develops at the back of the knee due to irritation, inflammation, or excess joint fluid. It’s often linked to arthritis, meniscal tears, or knee irritation.
Symptoms & What You May Experience
You may notice:
- Swelling or a tight lump behind the knee
- Stiffness or reduced bending of the knee
- Aching or pressure sensation when walking or squatting
- Pain into the calf if the cyst is enlarged or irritated
- Symptoms may come and go depending on activity
Some cysts are painless and only noticed when the knee is fully bent.
What causes Baker’s Cyst?
Common contributing factors include:
- Osteoarthritis or rheumatoid arthritis
- Meniscal injury
- Knee joint inflammation or cartilage wear
- Previous knee injury
- Repetitive strain or swelling in the knee capsule
The cyst itself is usually a sign of an underlying knee issue.
How We Help (At Victoria Park Osteopaths)
We aim to reduce irritation and improve knee function:
- Mobilisation and gentle manual therapy for the knee and surrounding joints
- Soft tissue treatment to reduce muscle tension and improve drainage
- Exercises to support joint function and stability
- Advice on pacing, swelling management, and movement strategies
- Support for associated conditions (e.g. arthritis, meniscal irritation)
- Referral for imaging or GP review if needed (aspiration/injection in severe cases)
Recovery Time & What to Expect
- Smaller cysts may settle in 2–6 weeks when the irritation is managed
- Larger or chronic cysts may persist but become less symptomatic
- Treating the
underlying cause is essential for long-term relief
When to Seek Medical Review / Red Flags
- Sudden calf swelling/redness (rule out DVT)
- Severe pain or rapidly enlarging cyst
- Locking or instability in the knee
- Symptoms unresponsive to conservative care
