Posterior horn of the lateral meniscus is within normal limits.Abnormal intrameniscal signal in the posterior horn of the medial meniscus may represent mucoid degeneration.ARTICULAR CARTILAGE AND BONE: There is generalized thinning of the patellar articular cartilage. There is focal thickening of the articular cartilage overlying the lateral femoral condyle.LIGAMENTS: Anterior cruciate ligament is intact. The posterior cruciate ligament is intact. The lateral collateral ligament complex is intact. The medial collateral ligament is intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
