Left knee pain and swelling, prior MPFL reconstruction and microfracture surgery Note that images are suboptimal secondary to the patient's body habitus and inability to use the appropriate knee coil.MENISCI: No significant abnormality noted.ARTICULAR CARTILAGE AND BONE: Again seen is susceptibility artifact within the medial femoral condyle relating to prior MPFL repair with thickening/scarring along the medial femoral condyle. An additional area of susceptibility artifact is noted within the patella centrally which is also postsurgical in nature. There is mild heterogeneity of the articular cartilage of the patella but otherwise there are no full-thickness defect. The femoral trochlea appears shallow suggesting dysplasia and there is mild lateral translation of the patella with respect to the femoral trochlea. This appears unchanged from the prior exam. The articular cartilage of the lateral and medial compartments is intact.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Limited exam demonstrating surgical changes of prior MPFL reconstruction with intact graft and scarring. There is otherwise no acute intra-articular pathology.
