Abstract: Hip joint cysts are a type of cystic lesion involving the hip joint and its surrounding soft tissues,mainly caused by degenerative changes or abnormal synovium.In imaging examinations, MRI and ultrasound examinations are crucial for the diagnosis of cysts.The clinical manifestations of hip joint cysts mainly include pain, swelling and compression symptoms. The treatment strategy depends on the size of the cyst, the severity of the symptoms and the nature of the primary disease.Conservative treatment can be adopted for asymptomatic patients,while symptomatic patients may require puncture aspiration or surgical treatment.In surgical treatment,hip arthroscopy has gradually become the preferred treatment due to its minimally invasive and high-precision characteristics.
