Left knee pain following injury MENISCI: No significant abnormality noted.ARTICULAR CARTILAGE AND BONE: There is a nondisplaced fracture of the lateral tibial plateau without definite intra-articular extension or articular collapse. An additional nondisplaced fracture through the fibular head is also seen. No full-thickness articular cartilage defects are identified within the medial, lateral, or patellofemoral compartments.LIGAMENTS: The cruciate ligaments are intact. There is edema type signal within the posterolateral corner of the knee raising the concern for posterolateral corner injury. The popliteal fibular ligament is not seen concerning for rupture and there is additional edema type signal near the attachment of the biceps femoris which may through the result of partial tearing or secondary to the bony changes described above. The popliteus tendon is intact.EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Nondisplaced fractures of the lateral tibial plateau and fibular head.2. Extensive edema within the posterolateral corner of the knee suggesting posterolateral corner injury. There is absence of the popliteal fibular ligament with additional edema near the attachment of the biceps femoris which may be the result of partial tearing or secondary to the adjacent bony changes.
