Reason: Evaluate left knee for medial meniscus tear History: Medial joint line pain x 4 weeks. MENISCI: There is mild intrasubstance signal within the body and posterior horn of the medial meniscus suggesting intrasubstance degeneration, but we see no discrete tear. Linear signal intensity within the anterior horn of the lateral meniscus extends through the peripheral fibers. While it is conceivable that this could represent a horizontally oriented tear, it is not necessarily of any clinical significance.ARTICULAR CARTILAGE AND BONE: There is fraying and partial-thickness clefting of the articular cartilage of the lateral facet of the patella. We see no fluid-filled defects of the tibiofemoral compartments. There is a small focus of subchondral edema within the medial femoral condyle that is nonspecific and may be degenerative in etiology or represent a peculiar contusion.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Small focus of bone marrow edema in the medial femoral condyle is of uncertain etiology but could be degenerative or perhaps represent a peculiar contusion.2. Mild degeneration of the articular cartilage of the patella.3. No medial meniscus tear. Possible small tear of the anterior horn of the lateral meniscus, which is not necessarily of any clinical significance.
