RESUMEN
[Summary] With an increasing higher failure rate from 50%to 70%after simple sutured surgery for rotator cuff tears , scholars have put forward the patch augmented biomechanics for healing massive tears .Research hotspots lie in the material structural and physiological properties .There are two types of rotator cuff patches , which are synthetic materials ( non-degradable and degradable type ) and biological rotator cuff patch ( autologous or allogeneic tissue , xenogeneic material ) .The synthetic materials rotator cuff patch is able to provide powerful biomechanics but has severe immune rejection , and the biomaterials patch provides excellent histological reconstruction in rotator cuff and accurate regulation of biological activity of metabolic degradation but lower biomechanical maximum tensile strength .This article reviewed the current common problems and progress in the application of the rotator cuff patches .
