Continuous loop graft preparation technique using Double-Z anastomosis. (A) A needle with #2 non-resorbable surgical thread was inserted from one side of the tendon cross section and passed through the tendon four times achieving a Z shaped anastomosis; (B) the needle passed in the tendon reversely achieving the second Z shaped anastomosis. The green dotted line showed the first Z shaped anastomosis and the red dotted line showed the second Z shaped anastomosis; (C) elevation view of the suture; (D) cross-sectional view of the suture; (E) same method was performed to sew another free end; (F) a surgical knot was knotted between the both free ends achieving a continuous loop graft.
