Result of mechanical evaluation. (a) Ultimate failure load of tendon humeral head complex. (Error bars indicate standard deviation) The ultimate failure load of scaffold group increased time dependently. It was significantly weaker at 4 weeks postoperatively than normal infraspinatus tendon; however statistical significant difference was not seen between 8 and 16 postoperative group and normal infraspinatus tendon. There was no significant difference between scaffold group and the reattach group at each time point. (b) Siffness of tendon humeral head complex. (Error bars indicate standard deviation) The stiffness of the scaffold group increased time dependently, however it remained significantly less stiff than that of normal infraspinatus tendon at each time point. Significant difference of stiffness was not seen between the scaffold group and the reattach group at each time point.
