Medial knee pain MENISCI: There is a complex tear of the medial meniscus consisting of a radial tear of the body and horizontal tear of the posterior horn. The horizontal tearing extends to the tibial articular surface with additional thin branching signal abnormality peripherally within the body of the meniscus. A slab-like focus of low signal intensity adjacent to the anterior horn of the medial meniscus likely represents a displaced flap fragment.The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is mild edema type signal within the medial tibial plateau underlying the torn medial meniscus. The articular cartilage of the medial, lateral, and patellofemoral compartments is intact. A cortically based ovoid focus of low signal intensity seen in the lateral aspect of the distal femoral metaphysis is likely the sequela of a healed nonossifying fibroma and is of doubtful clinical significance.LIGAMENTS: The cruciate and collateral ligaments are intact, including the superior band of the MCL.EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Complex tearing of the medial meniscus with probable displaced flap fragment. Additional findings are described above.
