  		Fig. 1A. —Normal anterior cruciate ligament graft in 32-year-old-man. Sagittal T1-weighted fat-suppressed spin-echo image shows proximal and mid portion of normal anterior cruciate ligament graft with low signal, uniform thickness, and position below roof of femoral notch. Tibial tunnel normally lies posterior to line drawn along roof of intercondylar notch.

  		Fig. 1B. —Normal anterior cruciate ligament graft in 32-year-old-man. Sagittal T1-weighted fat-suppressed spin-echo image obtained medial to A shows mid and distal portion of normal anterior cruciate ligament graft.

  		Fig. 2A. —32-year-old man with torn anterior cruciate ligament graft correctly interpreted by all three reviewers. Sagittal T1-weighted fat-suppressed spin-echo image shows discontinuity of graft. Curved arrow shows proximal portion of graft, and straight arrow shows distal portion.

  		Fig. 2B. —32-year-old man with torn anterior cruciate ligament graft correctly interpreted by all three reviewers. Sagittal T1-weighted fat-suppressed spin-echo image obtained in lateral compartment shows anterior displacement of tibia (tibial cortex is > 7 mm anterior to line drawn vertically along posterior femoral cortex).

  		Fig. 3A. —36-year-old man with localized anterior arthrofibrosis (arrow) correctly diagnosed by all reviewers. Sagittal T1-weighted fat-suppressed spin-echo image shows intermediate signal localized anterior arthrofibrosis extending anteriorly from insertion of anterior cruciate ligament graft.

  		Fig. 3B. —36-year-old man with localized anterior arthrofibrosis (arrow) correctly diagnosed by all reviewers. Coronal T2-weighted spin-echo image shows intermediate signal in arthrofibrosis.

  		Fig. 4. —23-year-old-man with normal graft incorrectly interpreted as localized anterior arthrofibrosis by all three reviewers. Low signal anterior to graft insertion (arrow) on T1-weighted spin-echo image was interpreted as localized anterior arthrofibrosis. No abnormality was described at this location at arthroscopy.

  		Fig. 5A. —36-year-old man with impinged anterior cruciate graft correctly interpreted by two reviewers and incorrectly interpreted by one reviewer as torn. Sagittal T1-weighted fat-suppressed spin-echo image shows increased signal in graft. However, some fibers appear continuous. Arrow indicates spur.

  		Fig. 5B. —36-year-old man with impinged anterior cruciate graft correctly interpreted by two reviewers and incorrectly interpreted by one reviewer as torn. Sagittal fat-suppressed T1-weighted image obtained medial to A shows that tibial tunnel extends anterior to line drawn along roof of intercondylar notch. Spur (arrow) is present at anterior margin of intercondylar notch.

  		Fig. 6A. —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 increased signal in graft (arrow) with deformity of superior surface due to impingement.

  		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.
