【 摘 要 】

Category:Sports.Introduction/Purpose:Large segmental Achilles tendon defects present a difficult problem to treating surgeons. Multiple procedures have been utilized to reconstruct these defects, but no studies have evaluated the comparative tensile strength of the various repair methods. Our institution has recently described the use of a dual semitendinosus allograft for Achilles reconstruction. Advantages of this procedure include eliminating donor site morbidity and providing an increased surface area for healing and tendon incorporation. Our study investigated the tensile strength of this novel technique as compared to a standard myofascial turndown procedure. We hypothesized that no differences in biomechanical properties would be found between dual semitendinosus reconstruction and Achilles myofascial turndown reconstruction.Methods:An 8-cm segmental Achilles defect was created in both specimens of nine matched pair, cadaveric lower extremities. The specimens in each pair were randomly assigned to ...
