Review Question - QID 8946

A 29-year-old male who underwent right hip arthroscopy for femoroacetabular impingement (FAI) two years ago presents for initial evaluation. He reports significant improvement in symptoms since the time of surgery but has never had full relief and continues to have activity related groin pain and discomfort with deep hip flexion activities. Review of arthroscopic photos from his index procedure confirm intact cartilage surfaces at that time. He has done extensive physical therapy without further improvement. Hip flexion, adduction and internal rotation reproduce his pain. Which of the following radiologic findings are indicative of the most likely reason for his persistent symptoms?
