Abstract
Rotator cuff tears generate shoulder pain and functional disability. The surgical treatment is performed through arthroscopy using suture anchors. The anchors can be metallic or non-metallic and have suture threads. Its function is attach the tendon to the bone to improve the healing process. However, the difficulty of passing and tying threads increases the surgery time and the costs. Therefore, the aim of this paper was developing an alternative implant to the anchors that does not use suture threads. The mechanical strength of the titanium implant and anchor was evaluated by using a simplified tridimensional model of the humerus and supraspinatus tendon. The results showed that the mechanical strength of the proposed titanium implant was adequate and the von Mises stresses for the new implant were lower than the stresses for the suture anchor.
