Fig 2 View of left knee after midline skin incision. A partial-thickness graft, taken from the most superficial layer of the tendon, is harvested from the central third of the quadriceps tendon, leaving its patellar insertion intact. Dissection is carried proximally enough to ensure that the graft is of sufficient length.

Fig 3 A subfascial tunnel is created in the lateral retinaculum with a clamp from the edge of the quadriceps tendon to the LPFL attachment site at the lateral epicondyle.

Fig 4 The end of the graft is secured with a No. 2 loop suture. The graft is then turned 90° laterally, twisted 180°, and passed through the subfascial tunnel with a passing suture.

Fig 5 The graft is fixed to the LPFL attachment at the lateral epicondyle with a knotless anchor. Arthroscopy Techniques 2014 3, e445-e448DOI: (10.1016/j.eats.2014.04.007) Copyright © 2014 Arthroscopy Association of North America Terms and Conditions
