Right hip pain with history of labral repair 5 years ago. ACETABULAR LABRUM: There is rounding of the anterior superior aspect of the acetabular labrum which may reflect prior surgery. Gadolinium contrast enters the substance of the anterior superior labrum at approximately the 1:00 position suggesting a partial thickness tear. The posterior labrum appears intact.ARTICULAR CARTILAGE AND BONE: Small foci of signal abnormality within the anterior superior aspect of the acetabular dome may be postoperative in etiology or represent degenerative cysts. There is thinning of the overlying articular cartilage. Posteriorly, the articular cartilage appears intact. Focal scalloping along the anterior aspect of the femoral head/neck junction likely reflects prior osteotomy. Just above this defect, there is slight prominence of the anterior aspect of the head/neck junction with an alpha angle of approximately 55 degrees. There is also slight prominence of the lateral aspect with head neck junction with alpha angles measuring between 55 and 60 degrees. On the large field-of-view images, the sacroiliac joints appear normal. Minimal irregularity of the body of the left pubic bone along the symphysis may represent mild degenerative erosion. Aside from the aforementioned changes, bone marrow signal intensity is otherwise within normal limits.SOFT TISSUES: The ligamentum teres appears intact. The musculature of the hip and pelvis appears within normal limits.
Findings suggestive of anterior superior labral tear with postoperative and degenerative arthritic changes of the anterior superior aspect of the hip joint and mild cam deformity as described above.
