[Capability for anti-stretch of 4 allogeneic tendon grafts]

To research the biomechanic property of 4 tendon grafts.The biomechanic properties of profound hypothermua froze tendon allogeneic grafts, profound hypothermua froze and dried allogeneic tendon grafts, autologous tendon grafts and allogeneic tendon grafts without intervention were tested.The biomechanic property of allogeneic tendon grafts with profound hypothermua freezing and profound hypothermua freezing and dying was better than that of allogeneic tendon grafts without intervention (P0.05). No significant difference was seen between the former 2 grafts and dried autologous tendon grafts (P0.05).Allogeneic tendon grafts with profound hypothermua freezing and profound hypothermua freezing and drying, have the same biomechanic property as dried autologous tendon grafts and can be used in clinical practice.
