Left knee pain MENISCI: There is focal partial-thickness radial tearing of the body of the medial meniscus. Additional faint linear increased signal intensity within the body and both horns appears to extend to this tear and may reflect additional tearing or intrasubstance degeneration.The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is edema within the medial femoral condyle anteriorly surrounding subchondral plaque-like foci of low signal intensity which may be degenerative in nature or represent small subchondral insufficiency fractures. The cartilage overlying these areas appears intact. There is a degenerative subchondral lesion within the medial facet of the femoral trochlea inferiorly with heterogeneity of the overlying articular cartilage likely representing focal full-thickness degeneration. There is additional mild superficial fraying of the articular cartilage of the patella. The articular cartilage of the lateral compartment is relatively spared.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Medial meniscal tear as described above.2. Bone marrow edema in the medial femoral condyle surrounding small subchondral foci of low signal intensity which may be degenerative in nature or represent small subchondral insufficiency fractures.3. Focal cartilage degeneration of the patellofemoral joint.
