Sagittal T2 FS MRI shows abnormal increased signal in the ACL in keeping with sprain (partial thickness tear). High T2 signal intensity involving the bone marrow of inferior patella, medial/lateral femoral condyles, and posterior medial/lateral tibial condyles is in keeping with bone bruising (though some of these areas of altered signal intensity could be due to disuse-related osteopenia).
