Female, 24 years old. Reason: Rule out ligamentous tear. History of pain and swelling in the left knee. Limited evaluation due to artifact from metallic hardware.MENISCI: There is a vertical tear of the posterior horn of the lateral menisci. The posterior horn of the medial meniscus is abnormally small and fragmented. The anterior horns of both the medial and lateral menisci appear intact.ARTICULAR CARTILAGE AND BONE: Postsurgical changes related to prior ACL repair with 2 metallic anchors within both the distal femur and proximal tibia. The posterior femoral tunnel extends through the cortex as seen on prior radiograph. The articular cartilage within the medial and lateral compartments appears intact. The arterial cartilage within the patellofemoral compartment appears intact without focal defect.LIGAMENTS: The anterior cruciate graft is not well visualized and likely torn. The posterior cruciate ligament appears intact. The collateral ligaments appear intact.EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Anterior cruciate graft is not well visualized and likely torn.2. Abnormally small posterior horn of the medial meniscus with fragmentation and vertical tear of the posterior horn of the lateral meniscus.3. Popliteal cyst which extends both medially and distally with debris which may represent meniscal fragments.4. Small fluid collection in the anteromedial aspect of the distal femur with surrounding inflammation of the subcutaneous fat which is consistent with a postoperative seroma.
