Nowadays, studies related to the psychological state of patients with chronic hip pain are still limited, and there is a lack of research on the characteristics of the psychological state of patients with chronic soreness from different pain sources. The goal of this retrospective cross-sectional study was to reveal differences between the psychological states of chronic hip pain patients with different pain sources. The main question it aims to answer is whether there are differences in psychological states among hip pain patients with intra-hip pain, extra-hip pain, and intra-hip combined with extra-hip pain.

Inclusion Criteria:

• The subject must be at least 16 years old and of sound mind；
• Chronic hip pain persisting for a duration exceeding 3 months.

Exclusion Criteria:

• Previous mental illness and cognitive impairment；
• Other serious illnesses such as heart failure, respiratory failure, malignant tumours, severe trauma and other serious illnesses;；
• Chronic pain lasting for more than 3 months in other parts of the body;；
• Use of prescribed opioid drugs exceeding 60 mg morphine equivalent per day or steroid analgesics.

Patients with chronic hip pain who visited the hip joint specialist outpatient clinic of the PLA General Hospital were included in the study. The diagnosis was made by the same docter based on clinical and radiological examinations, with a clear diagnosis of hip disease. Patients were divided into three groups according to the source of pain: intra-articular pain group, extra-articular pain group, and intra-articular combined extra-articular pain group. Intra-articular hip pain encompasses a range of conditions, including femoral acetabular impingement (FAI) and labral damage within the hip joint. Extra-articular hip pain encompasses conditions such as trochanteric bursitis and gluteal fasciitis. Combined hip pain represents a combination of both of these etiological factors.
