Right knee pain following injury MENISCI: There is truncation of both the anterior and posterior horns with absence of the majority of the body of the medial meniscus. There appears to be fragment displaced into the intercondylar notch just anterior to the PCL. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is mild thinning of the articular cartilage of the medial and lateral compartments. Heterogeneous signal within the patellofemoral articular cartilage represents mild degeneration. There are no fluid-filled full-thickness defects appreciated.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Absence of the majority of the medial meniscus with displacement into the intercondylar notch anterior to the PCL.2. Mild articular cartilage thinning without full-thickness defects.3. Lobulated marrow lesion within the distal femur may represent small cartilaginous lesion. Correlation with radiographs may be of benefit.
