Medial joint pain MENISCI: Marked destruction of the posterior horn of the medial meniscus without extension into the body. Only portions of the medial anchor remains given extensive fragmentation. Anterior horn is otherwise intact. Lateral meniscus is significant for moderate fraying of the inner edge. A small parameniscal cyst is observed adjacent to the anterior horn of the lateral meniscus.ARTICULAR CARTILAGE AND BONE: Mild thinning with focal 1.5 cm defect involving the posterior aspect of the femoral condyle, and overlying the medial meniscal abnormality described above. Mild overlying bone edema. Otherwise moderate changes most pronounced underlying the patella, without additional focal defects. Marrow signal otherwise intact other than scattered degenerative changes with numerous cysts, otherwise observed in the tibial plateau.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Large knee effusion with associated fragmentation and destruction of the posterior horn of the medial meniscus. See description and the associated overlying adjacent cartilaginous defect.
