A popliteal cyst measuring 0.6 x 6.1 x 2.3 centimeters is not considered serious if there are no uncomfortable symptoms. Popliteal cyst also means that there is a cyst in the deep part of the popliteal fossa, or the synovial bursa of the knee joint has bulged, which is not serious in itself, and if the current index is 0.6 x 6.1 x 2.3 centimeters, it is a relatively small cyst, and the symptoms of this type of patients are usually not obvious, and they can be resorbed by themselves without any special treatment. For popliteal cysts that cannot be self-absorbed, they can be cured through timely treatment. Clinical treatment is generally recommended to be surgical, mainly including traditional open surgery and arthroscopic surgery. When combined with inflammation and infection, glucocorticoid drugs such as dexamethasone and triamcinolone acetonide can be used as prescribed by the doctor. If popliteal cysts are detected, you need to go to the hospital for regular review to find out whether there is any risk of enlargement, rupture or bleeding of the cysts, and once any abnormality is detected, it is recommended that you seek medical attention and targeted treatment in a timely manner.
