Table 1 indicates the individual data (n = 10) of the fusion points (distances to the patella in millimeters) of the two-layered intermediate layer of the quadriceps tendon. The medial deep layer of the vastus intermedius aponeurosis fused with the aponeurosis of the tensor vastus intermedius (deep intermediate layer). The medial superficial layer of the vastus intermedius aponeurosis fused with the aponeurosis of the vastus lateralis (superficial intermediate layer). The meeting point of the superficial intermediate layer was always distal (23 mm, range 12 to 41 mm, SD +/− 0.9) to the meeting point of the deep intermediate layer. All elements of the quadriceps tendon fused over a region proximal to the patella ranging from 13 to 90 mm (Fig. 3b)
