Abstract
Arthroscopic superior capsular reconstruction (ASCR) is an option to treat irreparable rotator cuff tear. Different techniques have been used for ASCR. In this Technical Note, we use autogenous peroneus longus tendon to build a bridge for ACSR. Our technique is back-and-forth folding and fixation of the autogenous peroneus longus tendon under arthroscopy. This technique provides a simple and efficient method to repair irreparable rotator cuff tear.
