Male 16 years old; Reason: Right knee injury November 2014, patient jumped for a block during basketball, knee buckled, came down and fell, evaluate for ligament injury vs meniscus injury Due to the patient's body habitus, the high-definition MRI coil could not be used. An alternative coil was used, which slightly limits image quality and evaluation. MENISCI: There is a complex tear of the lateral meniscus, with attenuation of the posterior horn and displacement of meniscal tissue into the intracondylar notch. An additional vertical tear is present in the body of the lateral meniscus. There is a complete longitudinal tear of the posterior horn of the medial meniscus, which is seen on 6 consecutive sagittal slices. The body and anterior horn of the medial meniscus appear intact.ARTICULAR CARTILAGE AND BONE: Edema within the lateral tibial plateau likely represents bone contusion. A small subchondral cyst in the posterior aspect of the lateral tibial plateau with minimal depression of the overlying bone plate may represent additional sequelae of prior injury. Mild edema is present in the lateral femoral condyle and medial tibial plateau. Slight depression of the articular surface of the lateral femoral condyle above the free edge of the anterior horn of the lateral meniscus likely represents impaction deformity sustained at the time of injury. Evaluation of the cartilage is limited, but no focal fluid-filled cartilage defect is seen.LIGAMENTS: There is a complete tear of the anterior cruciate ligament. The posterior cruciate ligament is intact. The medial and lateral collateral ligaments are intact.EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Medial and lateral meniscal tears as described above, with displacement of the lateral meniscus into the intercondylar notch.2. Complete tear of the anterior cruciate ligament.3. Other findings as described above.
