Medial knee pain MENISCI: There is vertically oriented increased signal intensity within the posterior horn of the medial meniscus at its root likely representing a focal tear with mild associated edema in the underlying tibial plateau. There is also blunting and thinning of the free edge of the posterior horn of the medial meniscus likely representing mild chronic attritional tearing. There is an additional small defect within the anterior horn of the medial meniscus at its root; this could represent a small tear or a peculiar anatomic variant. The body of the medial meniscus appears normal.The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is diffuse thinning of the articular cartilage of the patella most pronounced centrally where there is near full-thickness to full-thickness articular cartilage loss along with small underlying subchondral cysts. The articular cartilage of the femoral trochlea also appears thinned with a subchondral degenerative lesion noted beneath the medial facet of the trochlea inferiorly and heterogeneity of the overlying articular cartilage which indicates more focal degeneration. There is mild heterogeneity of the articular cartilage of the lateral tibial plateau likely representing relatively mild degeneration. There are small tricompartmental osteophytes.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: There is focal intermediate signal intensity within the distal quadriceps tendon laterally which may reflect focal tendinosis but is of questionable clinical significance, and there is no focal fluid-filled tear. There is mild subcutaneous edema anterior to the patella tendon which is nonspecific.ADDITIONAL
