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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| tear | Patients diagnosed hip labrum tear by a hip arthroscopy or by a comprehensive clinical diagnosis through an orthopaedic surgeon with 15 years of experience | ||
| non-tear | Patients no diagnosed hip labrum tear by a hip arthroscopy or by a comprehensive clinical diagnosis through an orthopaedic surgeon with 15 years of experience |

| Measure | Description | Time Frame |
|---|---|---|
| labral echo homogeneity | Labral echo homogeneity is divided into homogeneous and heterogeneous. | After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants. |
| labral shape | Labral shape was divided into regular and irregular (there are potholes at the lip edge of the labrum or labrum are too full and swollen). | After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants. |
| labral hypoechoic cleft | Whether to tear was divided into yes and no. | After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants. |
| labral focal hyperechoic area | According to whether there is a focal hyperechoic area in the acetabular labrum, it is divided into yes and no. | After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants. |
| labral echogenicity | Echo intensity can be divided into Hypoecho, Isoecho and hyperecho. | After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants. |

| Paralabral cysts | Absent or Present | After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants. |
| Cortical Bone of Ilium | According to the continuity of the cortical bone of the ilium, it can be divided into continuous and interrupted. | After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants. |
| Max cross-section area of labrum | The largest area of the anterior superior labrum of the hip. | After the data collection and a week of data collation, two ultrasound physicians undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound of all participants. Take the average value of three times. |
| Hip Capsule Thickness | The anterior superior articular capsule of the hip was ultrasonically measured in the thickest area. | After the data collection and a week of data collation, two ultrasound physicians undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound of all participants. Take the average value of three times. |
| Thickness of Articular Cavity | The ultrasound was located at the longitudinal section of the femoral neck and measured the maximum thickness of the joint cavity of the femoral neck recess. | n and a week of data collation, two ultrasound physicians undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound of all participants. Take the average value of three times. |
