CONDITION - Knee, Baker's Cyst
If you have some swelling located in the back of your knee; you may have a Baker's Cyst. This is named after a physician who described it first, not because bakers have these cysts.
The cyst usually occurs due to some other problem in your knee such as arthritis or even a tear of your meniscus. The swelling from this problem causes fluid to build up in your knee. This fluid pushes out the weakest point of your joint capsule surrounding your knee. This is usually to the back portion of your knee capsule, and a cyst forms. The cyst has a valve made out of your joint capsule tissue. This valve can sometimes become clogged and the fluid becomes trapped in the cyst. Thus, even when the injury has resolved, you still have the swelling in the back of your knee. This is associated with pain usually described as dull and aching. The pain is worse with prolonged walking or standing. It is sometimes improved with rest, elevation and taking pain medication.
