Reason: Evaluate left knee for healing, changes, loose body since MRI in 7/15 History: Recurrent left knee pain. MENISCI: The medial and lateral menisci appear intact. ARTICULAR CARTILAGE AND BONE: There is slight lateral translation of the patella relative to the femoral trochlea. There is convexity of the femoral trochlea superiorly indicating dysplasia. Again seen is a full thickness defect of the articular cartilage of the medial facet of the patella, with what appears to be degeneration and delamination of the adjacent articular cartilage as well as superficial defects of the articular cartilage of the lateral facet of the patella. This appears similar or perhaps slightly progressed when compared to the prior study, although the bone marrow edema within the underlying patella has resolved. The tibiofemoral articular cartilage appears intact. We see no bone marrow signal abnormalities. LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons appear intact. The tibial tuberosity trochlear groove distance is approximately 17 mm, which is borderline abnormal.ADDITIONAL
1.Femoral trochlear dysplasia with slight lateral translation of the patella. Full thickness cartilage loss along the medial facet of the patella is again noted. Overall, the patellofemoral cartilage degeneration has perhaps progressed slightly when compared to the prior study. Small foci of low signal intensity within the joint anteriorly may represent loose cartilage fragments as suggested on the prior study.
