Pain in left knee, evaluate meniscus MENISCI: There is blunting of the free edge of the body of the medial meniscus as well as the posterior horn near its root. There is also a defect of the undersurface of the inner half of the posterior horn of the medial meniscus. There is a small focus of low signal intensity situated beneath the periphery of the body of the medial meniscus between the MCL and the underlying tibial plateau. These findings indicate a complex tear of the medial meniscus with displacement of meniscal tissue into the medial gutter. The anterior horn of the medial meniscus appears intact. The lateral meniscus also appears intact.ARTICULAR CARTILAGE AND BONE: There is edema within the medial tibial plateau beneath the torn meniscus. We suspect this is degenerative in etiology although this finding could conceivably represent a developing subchondral stress fracture. We see no fluid-filled articular cartilage defects involving the medial tibiofemoral articular compartment. There is full thickness degeneration of the articular cartilage of the femoral trochlea centrally and inferiorly with a cleft extending through the articular cartilage of the medial facet of the femoral trochlea. There is perhaps mild thinning of the articular cartilage of the patella inferiorly. Mild heterogeneity of the articular cartilage of the lateral tibial plateau posteriorly suggesting mild degeneration.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is within normal limits.ADDITIONAL
Complex tear of the medial meniscus with displaced flap fragment and other findings as described above.
