An illustrative case of a 27-year-old woman undergoing surgical hip dislocation for mixed-type FAI is shown. (A) The preoperative dGEMRIC map indicates severe acetabular cartilage damage in the anterosuperior quadrant. (B) The corresponding intraarticular damage during surgical hip dislocation confirms the cartilage degeneration (arrows). (C) The preoperative dGEMRIC map of the femoral cartilage indicates severe damage in the anterior peripheral aspect of the femoral head. (D) The corresponding intraarticular damage during surgical dislocation of the hip nicely reveals this peripheral femoral cartilage damage (arrows).
