58-year-old female with left knee pain. Evaluate for left meniscus tear and tibial plateau fracture. MENISCI: The lateral meniscus appears intact. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is a minimally depressed (1 mm) fracture of the lateral tibial plateau with the fracture line itself confined to the epiphysis, with bone marrow edema extending into the metaphysis. The fracture extends through the articular cartilage of the lateral tibial plateau just anterior to the posterior horn of the meniscus. Lobulated signal abnormality within the proximal fibula likely represents a benign enchondroma. There is full-thickness degeneration of the articular cartilage along the medial facet of the patella with relatively mild degeneration along the lateral facet. There is focal degeneration of the articular cartilage of the femoral trochlea, centrally. Relatively mild degeneration affects the medial compartment.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
Lateral tibial plateau fracture and other findings as described above. We see no meniscal tear.
