49-year-old female with history of knee pain. MENISCI: There is mild intrasubstance signal abnormality within the medial meniscus likely representing degeneration, but we see no discrete meniscal tear. There is obliquely oriented linear signal intensity within the periphery of the posterior horn of the lateral meniscus extending to the far peripheral aspect of the undersurface. While this may represent the interface of the meniscus with the meniscofemoral ligament of Wrisberg, its relatively lateral location within the posterior horn is more suggestive of a tear. Please note that this may represent an acute tear or a chronic healed tear given its position in the meniscus, and is of questionable current clinical significance. There is also poorly defined globular signal abnormality within the anterior horn of the lateral meniscus indicating degeneration with probable undersurface fraying.ARTICULAR CARTILAGE AND BONE: There is edema-type signal within the posterior aspect of the lateral tibial plateau subjacent to the aforementioned lateral meniscal tear. There is mild superficial fraying of the articular cartilage of the lateral tibia plateau more anteriorly and medially. There is mild degeneration of the posterior articular cartilage of the lateral femoral condyle. There is focal degeneration of the articular cartilage along the posterior aspect of the medial femoral condyle compatible with degeneration. There is moderate degeneration of the articular cartilage of the patella as well as focal degeneration of the articular cartilage of the trochlea inferiorly and centrally. There are small tricompartmental osteophytes.LIGAMENTS: The ACL, PCL, MCL, and LCL are intact. EXTENSOR MECHANISM: The quadriceps fat pad appears edematous which is of questionable clinical significance. The extensor mechanism is otherwise intact.ADDITIONAL
1.Findings suggestive of a tear of the peripheral fibers of the posterior horn of the lateral meniscus.2.Osteoarthritic changes as described above.
