4

Incise the capsule

L

Allograft Reinforcement of Tendon Repair (Optional)

1

Measure the dimensions of the graft

  • measure the size of the graft from anterior to posterior and medial to lateral dimensions
  • use a knotted suture measuring device

2

Prepare the graft

  • preoperatively prepare a size 0 braided suture with 6 knots
  • these should be spaced 1 cm apart
  • hold the measuring suture with a grasper on one end
  • pass the other end into a knot pusher so that the suture with its knots can easily slide back and forth through the eyelet of the knot pusher
  • most grafts require six suture points of fixation
  • space these points evenly like the odd numbers on a face of clock
  • use two suture for lateral fixation into the greater tuberosity
  • these are simple #2 braided permanent suture that are passed through the tissue with there ends tied together to prevent pullout from the graft
  • place short-tailed interference knot (STIK) sutures evenly spaced for posterior, medial, and anterior tissue fixation
  • make a midline ink mark on the lateral aspect of the graft as a reference point

3

Pass the sutures through the tissue

4

Remove the graft from the back table

  • bring the graft adjacent to the anterolateral cannula
  • clip a wet towel around the upper arm
  • place the graft on the towel

5

Orient the graft anatomically

6

Suture the graft

  • start sequential suturing posteriorly and progress medially and anteriorly
  • have an assistant select and hold the most posterior STIK suture
  • clip the grafts two lateral sutures to the towel with a hemostat and stabilize it
  • use curved suture hooks sequentially shuttle down to the four STIK sutures down the anterolateral cannula through the rotator cuff

7

Pass the suture hook

  • pass a suture hook starting posteriorly through and through the rotator cuff tissue
  • pass a shuttling suture out of the anterolateral cannula with a grasper
  • shuttle the free end of the corresponding posterior STIK suture through the cuff tendon and back out of the posterior cannula
  • repeat this shuttling technique progressing medially then anteriorly

8

Bring the graft into the shoulder

  • insert the graft through the anterolateral cannula
  • pull the slack out of all suture
  • this docks the graft at the aperture of the anterolateral cannula
  • roll the graft onto itself to facilitate passage through the cannula
  • use a push pull technique
  • as the graft is pushed down the cannula using a small thin grasper
  • pull the STIK ends of the suture from the posterior and anterior cannulas
  • once the graft is in the shoulder sequentially tighten ech suture end to unfold the graft and cover the repair site

9

Secure the graft

  • tie each STIK knot sequentially
  • use 2 push in suture anchors to stabilize the lateral edge of the graft over the lateral tuberosity
  • abduct the arm to the midposition of 45 degrees to access the lateral tuberosity
  • take the two limbs for the posterolateral suture into the posterior cannula
  • create a pilot hole in the anterolateral greater tuberosity
  • load the 2 anterolateral suture limbs into the push in anchor outside of the cannula
  • place the anchor through this cannula into bone
  • bring the posterior lateral suture limbs back into the anterolateral cannula
