Pain MENISCI: There is obliquely oriented signal abnormality extending through the posterior horn of the lateral meniscus consistent with a complete tear. A flap component is suspected. Slab like configuration of the body of the lateral meniscus suggests the possibility of a torn discoid meniscus, but this is equivocal. The anterior horn of the lateral meniscus and medial meniscus are intact.ARTICULAR CARTILAGE AND BONE: There is increased signal centrally within the articular cartilage of the patella indicating degeneration without focal fluid-filled surface defect. Bone marrow signal is within normal limits. No fracture or contusion.LIGAMENTS: ACL, PCL, MCL and LCL are intact.EXTENSOR MECHANISM: Quadriceps and patellar tendon are intact.ADDITIONAL
1. Tear of the posterior horn of the lateral meniscus likely with a displaceable flap component.2. Patellar cartilage degeneration without defect.
