The treatment time for popliteal cysts needs to be judged in relation to the severity of the condition and cannot be generalized, but it is best to treat them promptly. Popliteal cysts are a common lesion, mostly occurring in the posterior aspect of the knee joint bilaterally, in the form of a sac-like projection. If the cyst is small in size and does not cause significant discomfort to the patient, Chinese medicine massage, acupuncture, and physical therapy can be chosen to promote absorption of the cyst fluid according to the patient’s needs. If the cyst increases in size and compresses the popliteal median nerve and peroneal nerve pathway, causing soreness and swelling of the knee joint and impairment of flexion and extension, the patient needs to go to the orthopedic department of the hospital for appropriate treatment in a timely manner. In conclusion, popliteal cysts cannot be relieved by medication and must be cured by surgical intervention in the same department, but these diseases have a certain recurrence rate. Patients with popliteal cysts are advised to avoid rubbing or massaging them without authorization, and to consult an orthopedic surgeon in a timely manner to take reasonable treatment under the guidance of a doctor.
