Knee effusion, knee pain Motion degrades sensitivityMENISCI: Vertical signal under maladies observed posteriorly of the lateral meniscus concerning for a radial tear. The remainder of the lateral meniscus is otherwise intact and well visualized other than fraying of the inner edge. The medial meniscus however demonstrates more pronounced changes including a complex tear and degeneration of the posterior horn with extension to both the superior and inferior articular surfaces and moderate extrusion. The medial anterior meniscal body and anterior horn are otherwise intact, as well as the more midline portion of the posterior horn and anchoring element.ARTICULAR CARTILAGE AND BONE: Extensive cartilaginous thinning throughout all compartments. No discrete focal solitary specific defect involving the medial and lateral compartments, however severe erosion and destruction of the medial patellar facet is observed. Underlying marrow signal is grossly intact throughout.LIGAMENTS: Mild sprain of the MCL is observed with otherwise ligaments are intact throughout. Please note however that retinaculum, specifically the medial aspects are poorly visualized secondary to above-mentioned motion. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Large knee effusion with underlying moderate to severe degenerative changes including the medial meniscus and cartilaginous surfaces. See details above
