Surgical reconstruction of chronic achilles tendon ruptures using various methods.

Abstract

The purpose of this study was to evaluate the surgical outcomes of reconstruction of chronic Achilles tendon ruptures using various methods, including Achilles tendon allograft. Between October 2003 and March 2010, twelve patients with chronic Achilles tendon ruptures and a defect gap of >4 cm underwent surgical reconstruction with V-Y advancement, gastrocnemius fascial turn-down flap, flexor hallucis longus tendon transfer, or Achilles tendon allograft. The study group comprised 11 men and 1 woman. At last follow-up, all patients were assessed with regard to postoperative complications, self-reported level of satisfaction, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Achilles tendon Total Rupture Score, repetitive single-heel rises, single-leg hopping test, and ankle range of motion. The AOFAS scores increased from an average of 68.7 (range, 50-87) preoperatively to 98.0 (range, 88-100) postoperatively. All patients were able to perform 10 repetitive single-heel raises and single-leg hops at last follow-up. No patient experienced wound complications or deep infection. Seven patients were rated as excellent, 4 as good, and 1 as fair. Chronic Achilles tendon ruptures can be successfully treated by careful selection of the reconstruction method according to the length of defect gap and state of the remaining tissue. With an extensive defect, use of an Achilles tendon allograft can be a good option.
