A Prospective Case-control Clinical Study of the Ultrasound Imaging Reporting and Data System for Diagnosis of Anterosuperior Acetabular Labral Tears

A Prospective Case-control Clinical Study of the Ultrasound Imaging Reporting and Data System for Diagnosis of Anterosuperior Acetabular Labral Tears

The goal of this clinical trial is to develop an ultrasonic imaging reporting and data system for diagnosis of anterosuperior acetabular labral tears (ALT). Participants will receive a comprehensive clinical diagnosis or a hip arthroscopy to determine whether there is a torn labrum of the hip. Comparing the ultrasonographic characteristics of hip labrum in tear group and non-tear group, establishing diagnostic model is conducive to early diagnosis and differential diagnosis of this disease.

Inclusion criteria: a)18 years of age and above; b) Combined with clinical symptoms, signs, and MRI, a senior orthopaedic surgeon or a final arthroscopy will determine whether the labrum of the hip is torn.

Exclusion criteria: a) other diseases affecting the hip joint (tumors, infections and fractures); b) A history of hip surgery; c)BMI≥30 kg/m²; d) Pregnant patients.
