57-year-old female with right knee pain and possible meniscal injury. MENISCI: Fragmentation and increased T2 signal within the posterior horn of the medial meniscus is compatible with a complex tear that demonstrates both horizontal and vertical components. Increased T2 signal is also noted along the inferior aspect of the anterior horn of the lateral meniscus, suspicious for a vertical undersurface tear.ARTICULAR CARTILAGE AND BONE: Within the patellofemoral compartment, there is complete loss of articular cartilage along the medial facet as well as generalized thinning of articular cartilage along the lateral facet. Mild thinning of articular cartilage along the medial femoral condyle is also noted.Bone marrow edema is identified in the medial femoral condyle and medial tibial plateau, consistent with recent injury.LIGAMENTS: The cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Complex tear of the posterior horn of the medial meniscus with adjacent bone marrow edema.2.Findings suspicious for vertical undersurface tear of the anterior horn of the lateral meniscus.3.Complete loss of articular cartilage along the medial facet of the patella.
