66-year-old male patient with history of gout, pain and swelling of the left knee. Mild osteoarthritis on films with probable meniscal tear, knee clicking. MENISCI: The lateral meniscus appears intact. There is increased, multidirectional signal intensity within the posterior horn of the medial meniscus which likely represents complex tearing. Additionally the body of the medial meniscus appears macerated.ARTICULAR CARTILAGE AND BONE: There is full-thickness loss of the articular cartilage of the posterior aspect of the weightbearing portion of the medial femoral condyle articular cartilage. There is marked thinning of the articular cartilage more anteriorly. The articular cartilage of the lateral tibiofemoral compartment appears grossly intact. There is fraying and partial-thickness tearing of the articular cartilage of the lateral patellar facet.Edema and subchondral cyst formation is noted within the intercondylar notch of the tibia.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1. Complex tearing of the medial meniscus as described above.2. Chondromalacia most predominately affecting the medial femoral compartment.3. Edema within the intercondylar notch of the tibia.
