Fig. (7) Illustrations showing method of calculating the required tendon length to reproducing anatomical length-tension relationship. (A) Marking musculotendinous junction; (B) 22mm proximal to mark A; a simple stay suture knot applied at this location with superior border of pectoralis tendon; (C) mark on biceps tendon at DBG level; (D) mark proximal to mark C, at a distance equal to tunnel depth (TD) i.e if TD is 25mm, then mark D is 25mm proximal to mark C; (E) Proximal end of biceps tendon. D-E: is the segment of tendon to be resected. Tendon suturing should be started from mark D and then two suture limbs from tendon passed through the 4 holed EndoButton, as explained above.
