23-year-old female with pain and swelling. 9 months status post MPFL injury. Suboptimal examination secondary to inability to use the age to the coil and patient body habitus.MENISCI: The menisci appear intact.ARTICULAR CARTILAGE AND BONE: Note is made of metallic susceptibility artifact about the articular cartilage of the patella, centrally, which is presumably postsurgical in etiology, related to prior microfracture/chondroplasty. There is associated subchondral signal abnormality, likely degenerative in etiology. Again seen is a shallow femoral trochlea, superiorly, suggestive of mild dysplasia.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact. ADDITIONAL
1. Postsurgical changes of prior medial patellofemoral ligament reconstruction. The graft appears intact.2. Again seen is borderline patella alta and findings suggesting trochlear dysplasia which can be seen in patient's with patellar instability. Other findings as described above.
