Objective Absorbable patches are often used to enhance rotator cuff tears to reduce the failure rate of rotator cuff repair. At present, the lack of mechanical properties of absorbable patches is a major problem. The purpose of this study is to investigate the effect of directional stretching on the mechanical properties of different absorbable patches and evaluate its potential as a patch for rotator cuff repair. Methods The directional stretching process was used to prepare absorbable patches of different materials. The different directional stretching temperatures and draw ratios were set. The effects of different parameters on the mechanical properties of the absorbable patches for different materials were studied. Their thermal properties, crystallization and surface morphology were characterized. Results Under different directional stretching temperatures and draw ratios, the absorbable patches have different tensile strength and tensile strain. The tensile strength are 74±7 MPa, 97±6 MPa and 107±8 MPa (＞~40MPa for tensile strength of infraspinatus tendon of canine), respectively. However, only the strain of the patch made of poly-L-lactide-co-ε-caprolactone conformed to the flexibility of natural rotator cuff. Conclusions The directional stretching process can improve the mechanical properties of the absorbable patch. The absorbable patch made of poly-L-lactide-co-ε-caprolactone has the potential to reinforce the rotator cuff tear.
