Fig 2.

(A) A 2-0 Fiberwire looped suture is used to place a baseball stitch into the free end of the tendon. This provides control of the tendon and creates a secure construct for repair back down to the radial tuberosity. To thread the Proximal Tenodesis Button onto the sutures of the biceps tendon, (B) the first suture is passed by an assistant through one eye of the button and (C) out the other. (D) The first suture is retracted as the second suture is passed into the eye where the first suture exits, and (E) back through to exit through the eye where the first suture enters. The free ends of each suture should not be exiting from the same hole. This permits tensioning of the construct once the button is passed.
