Female 59 years old Reason: chronic ACL tear, 6 months of left knee pain evaluate for meniscus tear, chondral injury History: left knee pain. MENISCI: There is a partial thickness radial tear of the posterior horn of the medial meniscus best seen on image 10 of series 4. There is additional intrasubstance signal within the posterior horn of the medial meniscus that appears to extend from the free edge of the meniscus to the periphery, likely representing additional horizontal tearing. There is intrasubstance degeneration of the body of the medial meniscus, and the anterior horn of the medial meniscus appears intact. Increased signal intensity within the posterior horn of the lateral meniscus likely simply represents the interface with the meniscofemoral ligament of Wrisberg. We see no definite lateral meniscal tear.ARTICULAR CARTILAGE AND BONE: There is partial thickness degeneration of the articular cartilage of the medial femoral condyle just above the site of the aforementioned radial tear of the posterior horn of the medial meniscus. There also appears to be focal thinning of the subjacent articular cartilage of the medial tibial plateau. There is moderate thinning of the articular cartilage of the patella along both its medial and lateral facets, with subchondral cyst formation in the far medial aspect of the patella. LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
