Schlussfolgerung: Scaffold augmentation did not adversely affect the zero time strength of the tested standard
double row RCR. An increased ultimate load to failure was observed for two of the augmentation methods
(collagen patch as an interposition and decellularized dermis patch on top of the reconstruction) compared to the
non-augmented repairs. The results of this study showed that scaffolds (fibrin clot, collagen or dermis patch)
might be used for application of growth factors or cellular components in an "interposition" technique between the
bone and the tendon without jeopardizing the construct´s zero time strength.
