Resorbable (poly-L-lactide) and non-resorbable (polyethylene terephathalate) tendon augmentation devices (TAD) in conjunction with a pericardial adhesion barrier are designed to strengthen tenorrhaphies and are evaluated in an ovine extensor tendon deficit model in a short term study. Fifteen centimeters of tendon were resected and replaced with kangaroo tail tendon xenografts that had been cross-linked with 0.075 percent glutaraldehyde (GA) at a certain temperature for one or seven days. Compared with tenorrhaphies performed with Kesler sutures alone, both types of TAD were more effective at preventing tenorrhaphy dehiscence, and thus maintaining tendon function. The increase in tensile strength of TAD tenorrhaphies were also noted. Evaluation of the performance of tenorrhaphy augmentation devices with xenografts is required to further understand their usefulness for reconstruction of traumatic tendon injuries.
