54-year-old male with pain in the left knee. Evaluate medial meniscus. MENISCI: There is a small amount of increased internal signal within the posterior horn of the medial meniscus which does not extend to the articular surface and therefore is not a tear. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is increased T2 signal within the tibia involving both the medial and lateral tibial epiphysis which extends distally into the metaphysis. The increased signal does not extend to the cortical margin and is somewhat serpentine in contour and likely represents an unusual appearance of bone infarction. There is a small anterior osteophyte within the medial compartment. The patellar cartilage is intact. There is no significant thinning of the remaining intra-articular cartilage.LIGAMENTS: The collateral and cruciate ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1. Increased signal within the medial and lateral tibia which is somewhat serpentine in contour and likely represents an unusual appearance of bone infarction. 2. No evidence of meniscal or ligamentous injury.
