52-year-old female presents with right knee pain, evaluate for meniscal tear. MENISCI: Mild intrasubstance degeneration of the medial and lateral menisci, essentially normal for age. No discrete tear is identified.ARTICULAR CARTILAGE AND BONE: There is focal partial-thickness degeneration of the articular cartilage of the lateral surface of the medial femoral condyle just above the free edge of the posterior horn of the medial meniscus. There is a small full-thickness focus of degeneration of the articular cartilage along the medial facet of the femoral trochlea. There is perhaps mild superficial fraying of the articular cartilage of the lateral facet of the patella inferiorly, however this is equivocal. There is no significant bone marrow signal abnormality.LIGAMENTS: There is minimal edema type signal between the iliotibial band and the lateral femoral condyle which could conceivably represent a mild "friction syndrome", but this is equivocal. The cruciate and medial collateral ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1. Mild degeneration of the menisci without evidence of a tear.2. Small foci of cartilage degeneration as described above, not atypical considering the patient's age.3. Tiny Baker's cyst, not necessarily of any clinical significance.4. Minimal edema type signal between the iliotibial band and the lateral femoral condyle which could conceivably represent a mild "friction syndrome" in the appropriate clinical context.
