Reason: evaluate for ligament/tendon damage History: effusion, instability, knee giving out, increased patellar mobility. Due to the patient's body habitus, the high-resolution knee coil could not be used and the flex large array coil had to be used, resulting in slightly suboptimal image quality.MENISCI: Given the aforementioned limitations, the medial and lateral menisci appear intact.ARTICULAR CARTILAGE AND BONE: Mild edema within the posterior aspect of the lateral tibial plateau and also more anteriorly within the lateral femoral condyle, representing bone contusion. Evaluation of the articular cartilage is suboptimal, but we see no gross defects. The femoral trochlea is slightly shallow which may represent mild dysplasia.LIGAMENTS: The anterior cruciate ligament is poorly defined compatible with full-thickness tear. The posterior cruciate ligament is intact. The medial collateral ligament and lateral collateral ligament complex are intact.EXTENSOR MECHANISM: The visualized components of the extensor mechanism are intact.ADDITIONAL
ACL tear with associated bone contusions and joint effusion.
