Figure 3.

Pre- and postoperative axial T1-weighted magnetic resonance arthrography (MRA) images of a 33-year-old woman with posttenotomy left hip pain. (A and C) Preoperative images show no muscle atrophy, while (B and D) postoperative images demonstrate grade 2 atrophy of the iliopsoas muscle at the acetabular rim (arrow, B) and grade 1 atrophy of the quadratus femoris muscle (arrow, D). The postoperative MRA was performed 12 months after the patient’s labral-level iliopsoas tenotomy, and her modified Harris Hip Score at that time was 67 points.
