Left knee pain MENISCI: There is deformity of the posterior horn of the medial meniscus with a defect along the superior surface of the inner half of the horn and body and additional abnormal signal intensity along the undersurface of the posterior horn. A small focus of low signal intensity seen within the medial gutter beneath the body of the medial meniscus. The constellation of findings is suggestive of a flap tear perhaps with displaced meniscal tissue into the medial gutter. The anterior horn is intact.The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is mild degeneration of the articular cartilage of the weightbearing portion of the medial femoral condyle but we see no fluid-filled articular cartilage defects. Articular cartilage of the lateral compartment is intact. There is a small focus of full-thickness degeneration of the medial facet of the trochlea with mild superficial fraying of the articular cartilage of the patella. The bone marrow signal is normal.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Medial meniscal tear further described above which is suspected to represent a flap tear with displaced meniscal fragment.2. Cartilage abnormalities as detailed above.3. Small joint effusion and Baker's cyst.
