What is it?
It is a soft, usually painless mass that develops behind the knee. It is filled with liquid.
Causes
Baker cyst is seen in developing children after joint strains. In adults, it may develop due to other knee diseases such as rheumatoid arthritis, gout, and meniscus tear.
Clinical
Swelling behind the knee and sometimes in the leg, knee pain and stiffness in the knee are among the symptoms that may be observed.
Physical examination is important in diagnosis. It is best seen with ultrasonography. If surgical removal is planned, an MRI examination may be performed.
Treatment
Baker cyst in childhood is monitored by applying anti-inflammatory medication and elastic bandage. If there is no improvement within three months and there is pain, it is surgically removed. In adult Baker cysts, if there is a disease within the knee joint or a systemic disease, these are treated first. With the treatment of these diseases, regression of the cyst is observed. Draining the cyst with a syringe is not recommended as there is a high probability of recurrence. In rare cases where it is needed, it is removed surgically.
