The principle of popliteal cyst is still based on surgery, which is suitable for patients who do not see obvious shrinkage in a long time and rapid increase in size in a short period of time.
1. Popliteal cysts that have not been significantly reduced after a long period of observation: If popliteal cysts have not been significantly reduced after a year of follow-up observation and have a tendency to gradually increase, and affect the patient’s aesthetics and the normal activities of the knee joint, surgical resection can be considered.
2. Patients with rapidly increasing cysts within a short period of time: if the cyst volume increases significantly after 3 to 6 months of observation, surgical resection may be considered.
When the popliteal cyst appears, if it does not affect the aesthetics and the normal activities of the knee joint, it can be followed up regularly, and the ultrasound should be repeated once every 3 to 6 months to observe the change of the size. If the indication for surgery appears, surgical resection can be considered.
