Operative treatment for a diseased or elongated Achilles tendon often involves resection of diseased tissue and Achilles tendon shortening. If the amount of diseased tissue is minimal, a traditional Z-shortening technique can be used to achieve appropriate tendon repair and function, which involves making an incision along the longitudinal axis mid-substance of the Achilles tendon. This technique is limited in its ability to resect abnormal tissue due to the placement of the incision traditionally along the midline of the tendon. In this chapter we describe an original modification of the Z-shortening technique to allow for the flexibility to resect pathologic tendon tissue and preserve more normal tissue.
