BACKGROUND Recurrent defects after open and arthroscopic rotator cuff repair are common. Double-row repair techniques may improve initial fixation and quality of rotator cuff repair. PURPOSE To evaluate the load to failure, cyclic displacement, and anatomical footprint of 4 arthroscopic rotator cuff repair techniques. HYPOTHESIS Double-row suture anchor repair would have superior structural...

BACKGROUND Single- and double-row arthroscopic reconstruction techniques for acute bony Bankart lesions have been described in the literature. HYPOTHESIS The double-row fixation technique would provide superior reduction and stability of a simulated bony Bankart lesion at time zero in a cadaveric model compared with the single-row technique. STUDY DESIGN Controlled laboratory study. METHO...

BACKGROUND Rotator cuff tears are a significant cause of shoulder morbidity. Surgical techniques for repair have evolved to optimize the biologic and mechanical variables critical to tendon healing. Double-row repairs have demonstrated superior biomechanical advantages to a single-row. METHODS The preferred technique for rotator cuff repair of the senior author was reviewed and described in a...

We study a type of linear placement problem arising in detailed placement optimization of a given cell row in the presence of white-space (extra sites). In this single-row placement problem, the cell order is fixed within the row; all cells in other rows are also fixed. We give the first solutions to the single-row problem: (i) a dynamic programming technique with time complexity O(m2) where m ...

This paper investigates the reliability characteristics of a complex system having nine subsystems arranged in the form of 3x3 matrix in which each row contains three subsystems. The configuration of the row is of the type 2-out-of-3: F. Each subsystem has n units connected in series. The system fails if any one row containing three subsystems fails. The considered system analyzed incorporating...

BACKGROUND The single-row and double-row fixation techniques have been widely used for rotator cuff tears. However, whether the double-row technique produces superior clinical or anatomic outcomes is still considered controversial. This study aims to use meta-analysis to compare the clinical and anatomical outcomes between the two techniques. METHODS The Pubmed, Embase, and Cochrane library d...
