Revision Achilles Tendon Repair Using Posterior Tibial Tendon Allograft and Flexor Hallucis Longus Transfer.

Achilles tendon ruptures are common injuries seen by orthopaedic surgeons. A myriad of surgical options have been used in the management of Achilles tendon ruptures, but currently no gold standard exists. Re-rupture of Achilles tendon injuries occurs 1.7% to 5.6% of the time, and there has been no direct relationship demonstrated between complications and repair techniques used. The aim of this technique is to provide a method of fixation for the patient with an Achilles tendon re-rupture that provides a stable repair construct and mitigates the potential sequela of re-rupture. We describe the treatment of an Achilles tendon re-rupture with the use of a flexor hallucis longus tendon transfer and posterior tibial tendon allograft for repair of an 8.5 cm tendon gap.
