Photographs of anchors and the tendon damages caused by the anchors. (a) Photographs of four types of anchors studied, that is, the Healix Peek, Fastin RC, Bio-Corkscrew Suture, and Healix Transtend (with the Percannula system) anchors. (b) Photographs of tendon damage caused by the four types of anchors. All anchors were inserted through the supraspinatus and infraspinatus tendons without any cannula. (c) Photographs of tendon damage caused by the four types of anchors. The Healix Peek, Fastin RC, and Bio-Corkscrew Suture anchors were inserted through the supraspinatus and infraspinatus tendons without any cannula. The Healix Transtend anchor was inserted through the Percannula system, thus the hole in the tendon was caused by the cannula. The unit of the rulers was cm.
