PURPOSE The purpose of this study was to compare the clinical outcome of single-row (SR) and double-row (DR) suture anchor fixation in arthroscopic rotator cuff repair with a systematic review of the published literature. METHODS We searched all published literature from January 1966 to December 2008 using Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Coc...

In order to improve the opener of seeder and its lightweight structure, a new type is designed. The overall structure working principle single-ditch double-row are analyzed, structural parameters machete cutting soil guide board designed optimized. Using penetration angle included as test factors, field experiments were conducted. As indexes, resistance, sowing coefficient variation, depth vari...

In a previous paper, we introduced reflection equations for interaction-rounda-face (IRF) models and used these to construct commuting double-row transfer matrices for solvable lattice spin models with fixed boundary conditions. In particular, for the Andrews-Baxter-Forrester (ABF) models, we derived special functional equations satisfied by the eigenvalues of the commuting double-row transfer ...

INTRODUCTION: Orthopaedic surgeons have focused on improving the functional and structural outcomes of arthroscopic rotator cuff repair and labral repair through the development of biomechanically superior surgical techniques such as double-row fixation, suture-bridge fixation, and compression double-row fixation. To obtain the maximum benefit from these repair techniques, secure knot tying is ...

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...
