The purpose of this paper was to evaluate the effect of the material (tape or wire suture) and medial tendon passage (single or double passage) on the contact force, pressure and area at the tendon bone interface in order to identify the key factors responsible for this repairs´ success.engRotura da Coifa dos RotadoresRotator Cuff InjuriesWhy are tapes better than wires in knotless rotator cuff repairs?
