Posterior knee pain MENISCI: There is increased globular signal within the posterior horn of the medial meniscus. There may be a small focus of extension to the tibial articular surface (series 4 image 13/32) but otherwise there is no discrete extension to either articular surface. Additionally, the root of the medial meniscus appears intact and these findings directly representing intrasubstance degeneration. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is a small full-thickness cartilage defect within the lateral femoral condyle anteriorly measuring approximately 5 mm. There is associated underlying degenerative marrow signal abnormality. This is superimposed upon mild thinning of the articular cartilage. The articular cartilage of the medial femoral condyle also demonstrates diffuse thinning with a small partial-thickness defect of the femoral condyle anteriorly as well. There is diffuse thinning of the articular cartilage of the patellofemoral compartment without full-thickness defect.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Abnormal signal within the posterior horn of the medial meniscus thought to represent intrasubstance degeneration although there may be a small focus of extension to the tibial articular surface. The root of the meniscus is intact.2. Small areas of full-thickness cartilage loss within both the medial and lateral femoral condyle anteriorly.
