Knee pain following injury MENISCI: There is blunting of the inner free edge of the medial meniscus which may represent small tearing of the inner free edge. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is extensive full-thickness cartilage loss of the medial compartment with severe degenerative cystic changes in the underlying femoral condyle. Extensive marrow edema also affects the medial femoral condyle particularly posteriorly. No discrete fracture line is appreciated.There is mild diffuse thinning of the articular cartilage of the lateral compartment. The underlying marrow signal is normal.There is full-thickness cartilage loss in the medial patellar facet with underlying subchondral cystic change. This is superimposed upon moderate diffuse cartilage thinning.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1. Severe osteoarthritis and cartilage loss of the medial compartment with extensive subchondral cystic change and marrow edema which may a combination of reactive marrow changes and bony contusion. A discrete fracture line is not visualized.2. Additional moderate to severe cartilage loss in the patellar compartment with milder changes of cartilage loss in the lateral compartment.3. Blunting of the inner free edge of the medial meniscus suggesting free edge tearing/brain.
