Presentation
Indoor soccer injury. Landed on extended knee.
Patient Data
Edematous ACL. The anteromedial bundle appears continuous but is likely partially rupture, whereas the posterolateral bundle cannot be identified reliably along its entire course, suggesting complete rupture. Minimal lateral femoral condyle bone marrow edema.
Preserved menisci, PCL, collateral ligaments and cartilage.
Annotated series indicating anteromedial and posterolateral bundles of the ACL.
Case Discussion
Surprisingly isolated injury to the ACL with probably only one of the two consituent bundles being completely ruptured.
Often an ACL injury mechanism is associated with meniscal and collateral ligamentous injuries.
