Worsening right knee pain Due to the patient's body habitus the patient's knee could not fit in the dedicated knee coil, and the torso coil was used instead resulting in suboptimal image qualityMENISCI: The posterior horn of the medial meniscus is not visualized likely due to extensive chronic tearing and fragmentation. There is also attenuation and abnormal signal intensity within the body of the medial meniscus indicating additional degeneration and tearing. The anterior horn of the meniscus is also attenuated likely reflecting chronic attritional tearing.There is marked attenuation of the anterior horn and anterior aspect of the body of the lateral meniscus indicating extensive chronic tearing and fragmentation. The posterior horn of the lateral meniscus is relatively preserved.ARTICULAR CARTILAGE AND BONE: Severe osteoarthritis affects the knee, particularly the medial compartment, with areas along the medial femoral condyle and medial tibial plateau devoid of articular cartilage and associated with edema like signal in the underlying marrow.There is also full-thickness degeneration of the articular cartilage along the lateral femoral condyle above the posterior horn of lateral meniscus and moderate degeneration of the articular cartilage along the posterior aspect of the tibial plateau.There is moderate to severe degeneration of the articular cartilage of the patellofemoral joint.Tricompartmental osteophytes are also noted.A lobulated focus of abnormal signal intensity within the distal femoral metaphysis likely reflects a benign enchondroma.LIGAMENTS: The ACL is not visualized, presumably due to a chronic tear. The PCL is intact. The medial collateral ligament is bowed medially by underlying osteophytes but is otherwise intact. The lateral collateral ligament complex is intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Severe osteoarthritis of the right knee particularly affecting the medial tibiofemoral compartment with extensive tearing of the menisci.2. Nonvisualization of the ACL indicating a chronic tear.
