Knee pain Exam is slightly limited by motion artifact.MENISCI: There is increased signal in the posterior horn of the lateral meniscus which extends to the articular surface of the tibia and is consistent with complex tear. Additional linear signal is also noted within the anterior horn which is likely degenerative in nature. There is an associated parameniscal cyst within the medial gutter.There is increased signal is noted in the posterior horn of the medial meniscus which does not appear to extend to either articular surface is likely degenerative in natureARTICULAR CARTILAGE AND BONE: There is moderate diffuse thinning of the articular cartilage of the medial compartment with areas of near full-thickness loss involving femoral condyle anteriorly. Similar moderate diffuse thinning with scattered areas of near full-thickness loss are noted in the lateral compartment as well. Moderate diffuse thinning of the patellofemoral articular cartilage is noted without full-thickness defect although there are areas of near full-thickness loss involving the femoral trochlea.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: A minimal amount of increased signal is noted in the patellar tendon near its attachment upon the inferior pole which may reflect a component of mild tendinosis.ADDITIONAL
