A 27-year-old male patient underwent ACL reconstruction 3 years ago, the patient complained of knee pain and swelling. In assessment of the MRI knee, the conventional images shows mild knee joint effusion with intact ACL graft. Sagittal T2 image (A) at lateral femoral condyle level shows mild thinning of the articular cartilage upon the lateral femoral condyle posterior and middle segments (White arrows). On the post processing colour coded T2 mapping image: (C, D) The colour image along the articular cartilage of the lateral femoral condyle posterior and middle segments shows intrasubstance linear areas of blue colour with increased T2 value (as demonstrated within the curve image (B)) that corresponds to articular cartilage degeneration. According to the international cartilage Repair Society (ICRS) grading system, this corresponds to grade II cartilage
