In recent anatomical studies, an intervening muscle, between the vastus lateralis and vastus intermedius – named the tensor vastus intermedius - has been identified (Grob et al.; Rajasekaran & Hall 2016). Depending on the relation to the adjacent vastus lateralis and vastus intermedius muscles, different morphological types of tensor vastus intermedius were identified. The aponeurosis of the tensor vastus intermedius consistently fused into the middle layer of the quadriceps tendon and inserted at the superior medial border of the patella. As this muscle was previously attributed to other parts of the quadriceps muscle group, its role in the organization of the quadriceps tendon was unknown (Grob et al.).
