After surgery for popliteal cysts, the patient is usually discharged from the hospital in about a week. Because one day is needed before the surgery for preoperative examination to exclude contraindications to surgery, and then appropriate application of anti-infective drugs to prevent infection, the surgical procedure takes about three to four hours and requires anesthesia to be awake after returning to the ward; the next day, the wound is changed and the drainage is replaced, and then the wound is kept dry to avoid infection, usually with anti-infective and blood-stasis-activating The next day, the wound is changed, the drainage is changed, and the wound is kept dry to avoid infection. Usually the medication is changed once every three days and twice, after which if there is no obvious infection and redness, the wound does not ooze blood and fluid, and the skin is relatively dry, then you can choose to discharge. However, care should be taken to avoid contamination of the wound and to return to the hospital for another change of medication, which will take about two weeks for the wound to heal and then for the removal of the stitches.
