Altered signal intensity appearing hyperintense on T2 and STIR images in the vastus medialis. There is altered signal intensity in the oblique fibers of the vastus medialis in the femoral origin and in medial patellar retinaculum. These findings likely indicate strain/partial tear of the vastus medialis. Vastus Medialis is the most medially located of the quadricep muscles. The portion of the muscle just above the knee is known as VMO (vastus medialis oblique). This is important in stabilising the knee joint and often becomes inhibited following injury.
