41-year-old female with right knee pain and question of patellofemoral syndrome. MENISCI: There is fraying of the inner edge of the lateral meniscus. There is a horizontal, complex tear of the posterior horn of the medial meniscus with extension to both the superior and inferior surfaces and questionable extension to the posterior anchor. The anterior horn appears intact.ARTICULAR CARTILAGE AND BONE: There are mild degenerative changes of the undersurface of the patella. There is thinning of the medial compartment with focal defect measuring about 7 mm on the anterior aspect of the medial femoral condyle articular cartilage. Bone marrow edema is visualized at the origin and insertional sites of the ACL.LIGAMENTS: There is mild MCL thickening with minimal adjacent fluid without evidence of tearing. Further, there is thickening of the ACL with inflammatory change and partial tearing.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Degenerative changes of the articular cartilage and meniscal tear specifically described above. 2. ACL and MCL thickening as outlined above.3. Moderate to large joint effusion with questionable synovitis.
