Female 57 years old Reason: evaluate for torn cruciate ligaments History: falling, knee giving way MENISCI: There is marked truncation of the body of the lateral meniscus representing a large tear in the absence of prior meniscal surgery. There is also attenuation of the anterior horn of lateral meniscus, with increased signal that extends to the free edge and femoral articular surface, indicating additional tearing. There is also fraying/degenerative tearing along the undersurface and free edge of the posterior horn of the lateral meniscus. Medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is severe osteoarthritis of the lateral compartment with portions of the lateral femoral condyle and lateral tibial plateau devoid of articular cartilage. There is degenerative signal abnormality in the underlying subchondral bone. There is mild heterogeneity of the articular cartilage of the medial femoral condyle indicating mild degeneration. There is superficial fraying of the articular cartilage of the patella and focal thinning along the far medial aspect of the patella. There are small tricompartmental osteophytes.LIGAMENTS: Cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
Severe osteoarthritis of the lateral tibiofemoral compartment with extensive tearing of the lateral meniscus, particularly its body. Other findings as described above; the cruciate ligaments are intact.
