62-year-old female with pain along the lateral femoral condyle MENISCI: Globular intermediate signal within the posterior horn of the medial meniscus is suggestive of mild intrasubstance degeneration. Lateral meniscus is within normal limits.ARTICULAR CARTILAGE AND BONE: Marked thinning of the articular cartilage with subchondral cyst and reactive edema in the medial femoral condyle. Intermediate signal within the articular cartilage is compatible with degeneration without focal fluid-filled defect.Marked thinning of the patellar articular cartilage, primarily along the lateral facet, with combination of underlying subchondral cyst and bone marrow edema. There is fluid-filled laminar tearing of the articular cartilage along the medial aspect of the lateral facet.LIGAMENTS: The cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Articular cartilage defects along the lateral facet of the patella and medial femoral condyle as described above.2.Mild intrasubstance degeneration of the posterior horn of the medial meniscus.
