Which condition is Baker's cyst often associated with?

• A. Osteoarthritis
• B. Gout
• C. Rheumatoid arthritis
• D. Psoriatic arthritis

Answer: (A)

The main idea is that Baker's cyst forms from excess fluid in the knee joint, so it’s most commonly linked to degenerative knee disease. In osteoarthritis, the knee often develops chronic effusion due to cartilage loss and synovial irritation. This increased synovial fluid can track into the gastrocnemius–semimembranosus bursa behind the knee through a small valved connection, distending it into a Baker’s cyst. While inflammatory conditions like rheumatoid arthritis or other inflammatory arthritides can also produce knee effusions and cysts, osteoarthritis is the classic, most frequent association.
