MENISCI: The menisci appear intact.ARTICULAR CARTILAGE AND BONE: There is a focal full-thickness articular cartilage defect along the medial femoral condyle (image 11; series 901). There is bone marrow signal abnormality in the underlying area of the medial femoral condyle, likely degenerative. There is articular cartilage degeneration affecting the medial and lateral facet of the patella. There is fraying of the articular cartilage of the trochlea. Subcentimeter cystic focus in the proximal tibia likely represents a subchondral cyst.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact. ADDITIONAL
Degenerative changes including a focal full-thickness articular cartilage defect along the medial femoral condyle as described above. No evidence of meniscal injury, as clinically questioned.
