Fig. 6B. —30-year-old man with impingement diagnosed correctly by two of three reviewers. One of these reviewers and reviewer who did not diagnose impingement incorrectly interpreted graft as torn. All three reviewers incorrectly diagnosed localized anterior arthrofibrosis. Sagittal T1-weighted fat-suppressed spin-echo image shows enlargement of graft anterior to intercondylar notch (straight arrow), which very likely led to false-positive diagnoses of localized anterior arthrofibrosis. Spur at anterior margin of intercondylar notch (curved arrow) very likely contributed to impingement. Contrast material does not extend through graft on either A or B.
