43 year old female with knee pain. Evaluate for meniscus tear, chondromalacia. MENISCI: The posterior horn of the medial meniscus appears smaller in size relative to the anterior horn with blunting of the contour anteriorly compatible with a tear. The anterior horn of the medial meniscus appears normal. The lateral meniscus appears normal.ARTICULAR CARTILAGE AND BONE: There is generalized thinning of the articular cartilage of the patella with focal intermediate signal cleft along the medial and lateral facet with underlying subchondral bone marrow edema. There is a focal area of full-thickness articular cartilage defect overlying the medial femoral condyle with underlying subchondral bone marrow edema. There is focal subchondral bone marrow edema of the lateral tibial plateau. LIGAMENTS: The cruciate and collateral ligaments appear normal.EXTENSOR MECHANISM: The extensor mechanism appears normal.ADDITIONAL
1. Tear of the posterior horn and medial meniscus. 2. Generalized thinning of the articular cartilage of the patella with focal areas of articular cartilage defects as described above. Additional area of articular cartilage degeneration affects the medial femoral condyle.
