closure by combining the influencing factors . However, the success of a suture is limited by external
influences, e.g., defect size, retention force of the tissue, applied strain, and impact area.

Previous experiments have shown that the addition of a circular defect to the incision reduces the durability
of unstandardized wound closure with MonoMax to 0%. Standardization of the suture technique can

increase the durability to 100% . Increasing the impact area and using PDS instead of Monomax sutures
again lowered the durability. Our experiments revealed clear differences in the durability of sutures with
Monomax or PDS sutures. This is in contrast to the literature, which indicates only minor differences

between various sutures [12,21] .
