General Information About Baker's Cyst
Disease Details and Frequently Asked Questions
It is the herniation of excess synovial fluid in the knee joint outward through a weak point at the back of the knee, forming a cyst.
Osteoarthritis, rheumatoid arthritis, or meniscus tears that irritate the knee joint and lead to excessive fluid production are the most common causes.
A palpable swelling at the back of the knee, and a feeling of tightness and pain when the knee is bent or fully extended are observed.
The cyst can tear under excessive pressure. When the fluid spreads to the calf muscles, sudden and severe pain, redness, and swelling occur in the calf.
The size of the cyst and the underlying knee damage are determined using physical examination along with ultrasound or MRI imaging.
The underlying knee problem (e.g., meniscus) must be treated. In cysts causing complaints, the fluid is drained with a needle, and a cortisone injection is administered into the cyst.
