Semitendinosus Tendon Augmentation for a Large Defect after Achilles Tendon Rupture: Two Case Reports

Acute Achilles tendon ruptures usually occur in people between the ages of 30 and 40 years who participate in sports-related activities. Operative repair has become the standard treatment for acute Achilles tendon rupture in this group of patients. In chronic cases or if the gap is larger than 5 cm in revision surgery, end-to-end repair of the torn Achilles tendon is difficult and V-Y advancement will likely be insufficient. Often surgeons perform transfer of the flexor hallucis longus (FHL) tendon or use an Achilles tendon allograft, but it is difficult to harvest the FHL tendon in the deep midfoot area, and there are disadvantages to using commercial allograft. For this injury, we perform a V-Y advancement and a semitendinosus tendon transfer. Using a semitendinosus tendon in the repair of the Achilles rupture has to our knowledge not been reported. We report two patients in whom this operative technique was used. The procedure was simple and we had excellent results.
