This study tried to examine whether the utilization of an appropriate biocompatible tissue engineering (TE) scaffold in the augmentation of a chronic rotator cuff (RC) tendon or the repair of an abdominal hernia will result in tissue ingrowth, exhibit favorable histol. and increase biomech. strength of the healed tissue.It was found that the biodurable reticulated elastomeric matrix as a TE scaffold displayed pos. tissue growth with no undesirable effects.It also enabled the healing and repair of damaged tissue.These scaffolds have been shown to boost the mech. support of a chronic RC repair and solicit favorable healing of defects in the abdominal wall.
