Reason: meniscus tear/loose body? History: medial pain/mechanical symptoms MENISCI: There is extrusion of the anterior horn of the medial meniscus along with fragmentation of the posterior horn of the medial meniscus. There is also blunting through the body of the lateral meniscus, consistent with additional tear.ARTICULAR CARTILAGE AND BONE: There is significant medial compartment joint space narrowing with loss of the hyaline cartilage along the medial femoral condyle as well as medial tibial plateau with associated bone marrow edema within the medial tibial plateau.There is marked thinning of the patellar cartilage with a partial-thickness defect in the lateral facet.LIGAMENTS: There is lack of visualization of the ACL, consistent with complete tear. The PCL is within normal limits. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1.Complete right ACL tear.2.Extrusion of the anterior horn of the right medial meniscus as well as fragmentation of the posterior horn of the medial meniscus.3.Blunting through the body of the right lateral meniscus, consistent with tear.4.Osteoarthritis of the right knee particularly involving the medial and patellofemoral compartments as detailed above.
