After 14 days,the horizontal strength of the incision was tested in a digitised tensiometer.The SLWL ratio,suture tension and suture technique proved to have significant influences on the mechanical strength of the incision.Running sutures and especially closures with a ratio of between 4:1 and 8:1 proved significantly stronger than wounds People also askWhat is the tensile strength of collagen?What is the tensile strength of collagen?The collagen fibers reorganize,remodel,mature,and regain the tensile strength of up to 80% pre-injury.The collagen deposit in normal wound healing reaches a peak in the 3rd week,and maximal tensile strength is usually achieved by the 12th week.The Wound Healing Process WoundSource

Tensile strength was not sig-nificantly different at five days.However,wounds closed under tension showed significantly higher tensile strength at 7,10,14 and 21 days.Polynomial regres-sion reveals a cubic relationship between healing time and tensile strength where there are two periods of rapid increase wound strength.These results suggest
