63-year-old female with left knee pain, evaluate for re-tear of meniscus MENISCI: The posterior horn of the medial meniscus contains mixed signal and is blunted compatible with tearing. The body of the medial meniscus is near completely extruded medially. There is linear signal extending towards the articular edge of the medial meniscus at the body compatible with tearing. There is blunting of the posterior horn of the lateral meniscus compatible with a tear. Mild intrasubstance signal within the lateral meniscus compatible with intrasubstance degeneration. ARTICULAR CARTILAGE AND BONE: The articular surfaces of the medial tibiofemoral compartment are near completely devoid of articular cartilage. Abnormal marrow signal within the medial femoral condyle and tibial spine. There is severe thinning of the articular cartilage of the lateral tibiofemoral compartment.There are focal near full-thickness articular cartilage defects at the medial and lateral facets of the patella. Focal cartilage defect also seen within the intratrochanteric cartilage of the femur.LIGAMENTS: The cruciate and collateral ligaments are within normal limits.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Complex tearing of the posterior horn of the medial meniscus with near complete extrusion of the body of the medial meniscus. Peripheral tear within the body of the medial meniscus. 2.Blunting of the posterior horn of the lateral meniscus may represent a radial tear. 3.Severe osteoarthritis affects the knee, worst at the medial tibiofemoral compartment. 4.Articular cartilage defects, particularly at the patella as described above.
