47-year-old female. Status post OATS procedure to the MFC. Continued pain medially. MENISCI: Globular signal abnormality in the posterior horn of the medial meniscus consistent with intrasubstance degeneration, similar to prior study. No discrete tear is evident. The lateral meniscus is normal in signal intensity and morphology.ARTICULAR CARTILAGE AND BONE: Again seen are two adjacent osteochondral transplant grafts, each approximately 2 cm in diameter, in the medial femoral condyle. The marrow edema type signal in the more posterior graft has nearly completely resolved while the marrow edema type signal in the anterior graft is not significantly changed. The overlying articular cartilage is normal in signal and is flush with the native articular cartilage surface. The alignment of these grafts is unchanged with approximately 3.5 mm cortical concave stepoff between the two grafts.Marked thinning of the patellofemoral cartilage, most pronounced at the medial patellar facet, without underlying marrow edema, not significantly changed. New small area of deep fissuring of the lateral femoral trochlear articular cartilage. Mild diffuse thinning of the lateral femoral condyle articular cartilage, similar to prior study. Small tricompartmental osteophytes. LIGAMENTS: ACL, PCL, MCL, and LCL are intact.EXTENSOR MECHANISM: The quadriceps and patellar tendons are intact.ADDITIONAL
Medial femoral condyle osteochondral transplant grafts with near complete resolution of edema in the more posterior graft and similar amount of edema in the anterior graft. Unchanged alignment of these grafts with intact overlying cartilage.
